Mostly binance futures If i trade but now due to financial problems i can't trade so much and don't have enough funds...untfortunately
I look for top gainers sometimes they go even higher so if coin is up 20% it might trap If i see still coin can move up i move on to short altcoins i look for bigger Marketcap altcoins If they are up 5% then i Open short and If there is no news or any reasons for further pump i Open short.
Right now i see etc/usdt extremly over-bought and fake-out so i did Open short it now. Price 17.065$ on binance i think good entry for short with this price now.
But if you've got some strategy that you feel is gonna work for you, feel free to follow it until you see the effect of it being better.
Anyway, my tip to you being a newbie. Avoid futures.
