Just use a coldwallet and you will be fine.
I never used an exchange and I have a ROI of more than 50% in 4 months because of BTC.
Using exchanges is outdated IMO.
Innovate or get rekt mate, thats the game.
No exchanges, no price discovery, no price discovery, no value in BTC.
So you still active in crypto?
You are now in alts or you are out, fully?
