If you use Reddit, you may know that tip bots such as /u/tippr allow you to tip fellow redditors, in /u/tippr’s case, with BCH. Another Reddit bot has recently been discovered that attempts to gain access to Reddit accounts that have sent tips, and if successful, transfer out any balance the account may have with tip bots to the bitcoin cash address: 1Dn1uint1pMTrNXGyE3hQzyL6FJ8jpS1SD. Here are the methods with which you can secure your Reddit account against attackers. Obviously, protecting your Tippr BCH tips is only one benefit of having a secure Reddit password.

Use a secure Reddit password

Secure passwords will always help improve security. When choosing a password, length is better than most other security practices.  Otherwise, make sure that you do not use birthdays or things linked to you personally.

Use two-factor authentication on your account

Two-factor authentication means that when trying to log into your account, you are required to input a randomly generated, one-time use code alongside their password, this is accomplished using any two-factor authentication application that supports Time-based One-Time Password Protocol,  the Android and iOS apps Authy and Google Authenticator are recommended. You can read the full two-factor authentication setup guide here and there is a short explanation of enabling two-factor authentication below.

Enabling two-factor authentication requires you to be a subreddit moderator. You can become a subreddit moderator by creating your own subreddit. If you are a subreddit moderator you can find the option to enable 2FA on your preferences page. Reddit will ask you to confirm your email and password during the process of enabling two-factor authentication.

Level 3 SSN, Scan of Photo ID, Selfie holding your ID $25,000 USD
Enhanced Verification Contact Support Greater than $25,000 USD

Poloniex Exchange Verification Process

Poloniex’s verification process is simple and is only required for withdrawal of currency. All users will need to enter their full name, date of birth, and address to start, after which webcam based verification of photo ID and possibly a utility bill will take place – This involves holding the requested identification document next to your face and allowing your webcam to take an image.

Once verification is confirmed users can withdraw $25,000 equivalent per day, which can be increased by contacting Poloniex support. It is recommended that users get verification before beginning to trade, as without verification you can only deposit and trade currency.

The exchange has a tiered fee system using a maker and taker model. In this model, trades happen between makers and takers, where the taker places an order to match a maker’s order. Because makers add liquidity to the market they are given a fee discount. Fees are calculated as an average of trading activity, with higher activity leading to lower fees. You can find a breakdown of volume to fees available here.

top cryptocurrencies november 2017

Since the release of Bitcoin, cryptocurrencies and blockchain technology have taken the world by swarm. Typically, a cryptocurrency is differentiated from a normal, fiat, currency because it is decentralised, not centralised. Cryptocurrencies allow internet users to transfer value in a peer-to-peer (p2p) system without middle men. This means that payments cannot be censored, and financial friction will inevitably be lessened internationally. Over the last several years, we have seen all of these use cases slowly come to fruition.

Where Bitcoin and most other altcoins are only psuedonymous, new cryptocurrencies such as Zcash can actually be provably anonymous. Still others, such as Ethereum, have created decentralised platforms for smart contracts – paving the way for our decentralised future. Some of these cryptocurrencies use Proof of Work (PoW) while some use Proof of Stake (PoS) – still others use a hybrid model, or a different type of consensus algorithm to address the Byzantine Generals’ Problem altogether.

No matter how you look at it, since the release of Bitcoin in 2009, the cryptocurrency space has evolved – and is still evolving. Now that 2017 is coming to an end, let’s take a step back and look at the top 25 cryptocurrencies from 2017. Use this list to find the best cryptocurrency for you!

Where can I buy these cryptocurrencies? You’re in luck! BlockExplorer also has a Top 25 Cryptocurrency Exchanges List of 2017 that will let you compare different exchanges around the world and choose the one that’s best for you.
