i had lost a good portion of it trying to profit trading with altcoins (bad option).
What do you think people? go all in btc or diversify a little on alts?
You already have a bad experience with alts. You should learn from it. If I were you, I would focus on building my wealth on bitcoin. Buy some bitcoin in small portions regularly so that you could cost average the price. You never know. You made mistakes during the last crypto bull run, maybe you can redeem yourself on the next.
