What kind of mindset should I have to stay in Bitcoin? And I think Bitcoin is about to hit the highest price ever, so how should I plan my dca strategy?
Well, if you want to stay in BTC and then invest the highest part of your portfolio into BTC then your mind will remain toward BTC all the time, and you will be visiting the exchange again and again just to see what price BTC has now. Besides this, try to learn what BTC is proposing and what makes it the king of alts.
And if you want to do DCA in BTC then DCA is a strategy, you simply have to segregate funds from your earnings, and should invest them into BTC after an equal interval of time. The following time is not restricted, nor is the funds to invest in.
