Pretty nasty day, but volatility in a new market is to be expected, each time cryptos take a massive beating and then come back it adds to their legitimacy. Not something I would put my money in but I think the same applies as any long term investment in that you should set it and forget it for a reasonable time frame. You invest in an idea or a story and those things really don't normally radically change day to day. If you think it has a future then invest, if something changes on a macro level that shakes that thesis then sure sell but most retail traders are just looking for a quick buck and just like other asset classes they are just going to be taken for a ride. Trading and investing are very much not the same thing.
