If you are good in reading the charts, you might wanna go for shorting BTC but it’s considered high risk as the market cannot be predicted. Since BTC is the world’s most popular and the ultimate mother of all cryptocurrencies, the less risky way is just simply holding it because you can’t deny that BTC’s value will rise once again.
Holding is the safest way, but if we can’t wait then better convert to usdt especially if your in profit already those who have extra money can buy more during that time or do day trading to take profit whenever the price dump and increase a bit, though it requires a knowledge in trading and more of monitoring. I regretted the time I needed to convert my BTC due to emergency even the price is too low, and most ICO altcoins losing their value, that’s why it is okay also to convert and wait to buy back once the market is in status of recovering since we can’t guarantee when the price will be better again.
