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.

This is too high, damn! They are really trying so hard to discourage people from getting involved in owning crypto assets with such ridiculous high-income tax, I guess it is up to the citizens to decide if they are willing to accept regardless of the high tax imposed by the government, whether big or small investors will feel the same impact of 30%, and the moment people are okay with this I don't see it changing, 10 - 15% would have been reasonable.
