Finally, I’d say that trading is full of complexity and unpredictability, there’s not a single guarantee of actual success, but for those who can’t resist the temptation and are actually willing to take the risk, they should be super careful and always remember to use not more than 10% of their holdings in order to be on the safest side.
I have a problem with people even having to use part of their Bitcoin holdings to trade. I believe in separation of concerns and precision which spurs effectiveness.
I think if you must trade, trading wallets should be handled separately and holding wallets should be treated separately. Your accumulation amount for your holdings and your portfolio should not be tampered with, then if you must trade, plan a different fund buildup for it which shouldn't in anyway be intertwined with your Bitcoin holdings, your consistency in buying Bitcoin or your buying amounts.
I reinstate the belief that involvement onto trading during your accumulation journey isn't the best practice since it may lead to divided focus, so I believe your accumulation journey would be more effective when you focus on Bitcoin accumulation alone and divert the money intended for trading to buying Bitcoin to increase your aggressiveness.
Hopefully with that action they are not using exchange wallet to trade since they are putting their selves on multiple risk for that situation. Also they are bound to spend all they have with that matter especially if they get frustrated and want to chase some profit.
So better choose to have other multiple wallets for HODL use and the other one is for other activities. But I don't also recommend people to engage with trading especially if they look forward to gain profits since provably losing and winning will be repetitive cycle then they might just waste their time also will not get anything from that situation. Better if they spend their money buying Bitcoin since this provably give them good chance that they can sustain this type of investment.
