3. Taking profit to actually invest into altcoins because there is predicted alt season coming with some Altcoins been rumored to be able to do 5x or more is a capital gambling which mostly results more into losses than profits.
This is the biggest mistake that I've done years ago. Thinking that my BTCs converted into the altcoins of my choice would give me more profit than by just holding Bitcoin.
A huge mistake that I've learned of and that's why after that mistake, if I want to invest in alts, I just let it pass and in no way I am going to use my BTCs for taking profits.
I guess with this bull run, if someone has took profit and sold some BTCs to own their dream house. I won't argue with that.
A dream, and a house that has become true because of Bitcoin.
