Always convenient to talk about fee #FundingFeesExplained . Currently around the threshold of -1% /4h like coin $FUN , with a leverage of 30X, then in 4h %ROI >=30% only then is there profit. If within 24h you have %ROI=100% then you lose 6*30%-100%=80%. That's a really terrible number, so I also keep away from these coins for safety. Not enough to make a living.
