even presuming any abilities to make money with trading.
That feels like a little slap

But yes! it's for the best there's a higher probability of loosing it comparing to just holding it and continue shaving it slowly, refilling when it's needed.
My presumption in regards to when sustainable withdrawal is meaningful to employ is after you have already reached a status of over accumulation of BTC
I think the
over accumulation of BTC should be on bold and yeah only individual can decide that but there're certain level that you should know you've reached a level to Start withdrawing which might even depend on level of entries I.e I can't compare my level of entry to someone who has started 10 years ago(the price of entry really matters).. so it might take time to reach a status to be compared as to that other person [think the status should be a F*ck you status right??]
That's true thinking of withdrawing strategy when one haven't gotten to far with is accumulating is sign of poor investment management, aslong we embarking on a long-term investment in Bitcoin we shouldn't be thinking of withdrawing now only for those that have gotten themselves some nice amount of Bitcoin stash.
Exactly you're on point I_Anime, a beginner should stay far from thinking of a withdrawal strategy.
