I'm new to steemit so I'm just getting up to speed on how it all works. That caveat aside, you bring up an important topic.
The crypto markets are extremely volatile at this point in time. A single news item such as the troubles with Binance and Japanese regulators can push prices up or down with breathtaking speed. Even worse, a few hours after the bad Binance news hit, another article showed up about Binance moving to Malta which is a much friendlier jurisdiction when it comes to crypto. If you are trying to trade the dips and peaks you have to sit in front of your computer all day and watch for these types of announcements so you can react. Who has that much time?
The real question for anyone investing (not day trading) in this space is not today's price but what crypto and blockchain will become as the markets mature. Riding out the volatility takes nerves of steel. If you really believe that this tech is going to transform business and finance, then you should hold on for the ride. Just don't put any more into your portfolio than you can afford to lose.
