I remember in 2020, I knew bitcoin would hit at least $30000, but surprisingly it goes above. When bitcoin got to $20000, I opened a long position from 50 to 125x using BTC/USDT perpetual future and all got liquidated as bitcoin price fall slightly most of the time before it continues its bull market.
That was so much exposure there. Even at 50x, it's still considered to be high risk let alone the 125x you increased it to. Once it comes to trading, you've to remember that nothing is certain. Even when you know price is going to get to a certain level and you're very sure of it, it's still not advisable to take unmitigated risk. With 50x price wouldn't have liquidated you at the level it did with 125x. Perhaps, you still would've been safe (and saved) and in profit on that trade.
The problem is that it is not good to leave your coin on exchanges, the best and safe place your coin can be are on wallets, noncustodial wallet to be specific, which you can hold and protect its private key.
No serious minded trader will agree to that and say they won't keep their money on exchanges. Whenever I read about those advising against keeping money on exchanges, I know who truly doesn't trade for a living or who doesn't even trade at all or that often.
This question is funny though, but just want to see the opinions of others about this. Or someone should not hold using leverage because of the reason of risks of going for leverage trading for maximising profit?
I just came into this leverage trading in cryptos newly and I haven't done much trading with it. For the few I've done I leveraged on 5x or 10x and that's with short time trades. I haven't held a future trade for more than 36hrs. If I'm to hold a trade on leveraging, it certainly won't be more than those parameters I've been using.
