I usually don't prefer futures trading; I can't accept this kind of loss. For newbies, leverage trading is more dangerous. When they lose a big amount of funds, then they might lose interest in cryptocurrency and Bitcoin. Those who are highly skilled and experienced and can afford to lose might do leverage trading.
I can tell you for fact that this is the major reason why most people call cryptocurrency a scam, trading and investing on shit coins for quick gains is the reason why they are actually people still calling cryptocurrency scams. You cannot see any holder or even profitable trader calling cryptocurrency a scam or even quitting.
5 to 6x leverage is not high leverage to me but increasing it is where high leverage begin. There are people that are using 10, 25, 50, 100, 200, 500 leverage, these are the high leverage that some people use. These people are not traders but they are thinking they are traders, not knowing they are gambers.
Yes the leverage below 10x is actually regarded as not so high leverage but seriously it depends on the coin you’re actually trading, a coin like bitcoin I would say it’s actually a reasonable leverage although there are still periods that bitcoin is extremely volatile like we say this week. But if the coin in question is actually all this alt coins, 5x leverage is still considered high in my opinion and once a trader is trading it I usually advice very tight stop loss and most especially not going against the trend because this is where people gamble in trading
