Is it bitcoin or altcoin, if it is altcoin, can you specify?
Bitcoin price is volatile but altcoins price are more volatile, future trading can be leveraged up to 100x for bitcoin and coins like ethereum while 50x for other available altcoins. Which coins have you been using and which is bringing you profit?
What I mean is BTC/USDT or ALTCOIN/USDT.
I think what that matters is the leverage used, but I have been experiencing liquidation at 3x leverage for altcoins in extreme volatile market, when I calculated it for bitcoin, the trading fund would not have liquidated if i used bitcoin because the liquidation price is still most of the time far from the price.
I will not talk more about manipulation because I have seen bitcoin future market price manipulated in a way many people's coins are liquidated in just few minutes, but I think I have seen it happened in bitcoin future market ones on the exchange I am using but this happened frequently with altcoins in volatile market.
In future with leverage, it only makes sense to trade bitcoin. The reason isn't only because of the volatility but also because BTC generally is an independent variable by which I mean when you trade BTC you generally have to worry only about the BTC chart, but when you trade altcoins what you have to worry about is both the altcoin chart as well as the BTC chart, so if BTC falls you will unnecessarily hit your liquidiation no matter how strong your trade was. This is why only bitcoin future trading makes sense, but that also I feel only till 10x or 20x leverage, above that holding anything for a few hours is quite risky.
