For me personally, i would say to trade what amount you can afford to lose. Because the outcome will be depends on the amount you trade wether you loss or win. Especially on trading crypto which so volatile and if you don't use to set stop limit there's a high probability the amount you trade will disappear immediately. And even let say you have risk management and its 1:2 ratio. Make sure that 1% , will not hurt you Coz after that for sure you will chase your losses which a bad idea as it's the main reason traders burned their account.

So trade responsibly, set a limit to trade and you must know what will be exact amount to risk to avoid regrets. That's my advice.
