Yes, ₿itcoin is like any other currency and therefore permissible to make money (ie more fiat) from money exchanges like you would from gold to silver etc. Just make sure you understand & know the rules of money exchange so as to avoid Riba.
I have a video on YouTube that will help you with this.
ALSO, any platform that does not allow you to withdraw either currency is not permission or to use. For money exchange to be permissible you need to have full ownership of your money. If you can’t withdraw, then it isn’t yours.
Last piece of advice, you need to have the correct metric when measuring your ‘apparent success’. If you’re not building a greater amount of #BTC with your activities, then you’re losing out and you would be better off just DCA’ing your BTC. You DONT want more fiat, you want more BTC. If I told you that there was only 21 stones in the park but an infinite amount of grains of sand, which one should one try the acquire?
