I prefer the strategy after selling altcoins into fiat currency and then entering the stable coin I chose usdt because it can secure profit and take a chance when usdt goes down when altcoin goes up and when altcoin goes down usually usdt goes up and then sells it to buy other altcoins
Stable coins is not moving that much but crypto due to it's volatility the value against usdt is really good if you are into
day trading, you can pick which assets that's expereincing downfall,
Buy and wait, then convert it back to usdt once the market rise up, short term profits is far better than waiting for long
time but missmanaged your timing.
