Bitcoin Gold and Verge have already experienced 51% attacks, and the results are crippling. Beyond the money stolen during a double spend, a 51% attack decimates any reputation and trustworthiness held by that crypto. If a crypto is 51% attacked it is usually removed from all exchanges and users dump all their coins. The Bitcoin protocol has always had a design that gave 10 minute average time between blocks being mined; which means 10 minutes before you have a single confirmation. It normally considers 6 block (6 confirmations, at an average of 10 minutes each) to be enough to avoid a double spend. Tether, a U.S.-based cryptocurrency exchange with trading code “USDT” has been discovered to have a nasty loophole enabling a “double-spend” exploit. In cryptocurrency language, this happens when a certain number of Bitcoin or other digital currency covertly makes two or more deposit transactions using Blockchain technology. The problem of course is the payee can’t verify that one of the owners did not double-spend the coin. A common solution is to introduce a trusted central authority, or mint, that checks every transaction for double spending.
