I will say you should have a number of strong coins (many would say 5 to 10 ) - but You should have a plan for when to get out -- what multiple of profit you're wanting (And Have it written down), so that your emotions won't interfere later down the road.
Perhaps do up a spreadsheet, with all the #altcoins you own listed down. And put down the PRICE you'd be happy selling at. (it can be a Range - this is probably best, so that IF u miss the exact price pt you can still be able to sell & lock in profit )
GOOD LUCK
Thx for the advice!
By the way, I wrote a spreadsheet template the other day, to help me save time while updating it. If you're trading on something other than Binance, you may need to make some changes. Enjoy!
