So many people are saying they believe in cryptocurrency, but they don't even really understand where the potential comes from. BLOCKCHAIN is the big technology here. Jokes coins and most designed as an alternative to fiat money will mostly be weeded out. What happened before the dotcom bubble is basically happening here. We had way too many companies using the internet for stupid things with no real purpose. Once the bubble bursts on these cryptocurrencies, the ones actually utilizing blockchain to DO SOMETHING REAL will come to the forefront and flourish. If you believe in the tech, then just buy and hold "good" coins. If you don't care and you're trading short term, that's a totally different story.
There are good coins out there that you shouldn't really have to worry about long term even in a bear market. Civic is a coin using blockchain to control and protect identity info. An up and coming coin is Hadron that uses it for distributed AI computing. Anyways, long story short, there's no need to panic. Market corrections are normal. Believe in the tech.
