Well, the result will be not far from that anyway. But thanks for correcting me.
It is far off. Allow me to edit your post:So 4 altcoins have $670.75 income last year and bitcoin only portfolio could bring $733.85 $1552.55 what is $63.1 $881.80 more and no need in searching for gem altcoin. This result gives a lot of food for thought.
You took the average for Bitcoin during the year, instead of the final result.
