That's not a good strategy. You always diversify your investment funds, no matter the amount of them. It's better, in any term, to put in 10 different assets $10 in each asset, rather $100 to just one.
is that really true though? diversifying $100 to 10 coin, just feels like a lot of headache just probably for $3 gain in 30% price increase.
instead if you don't diversify you can spare yourself of headache and still profit, I mean most alts rally in unison anyway, if it dumps all dumps and if it rise all rise so I think at this point diversification is just waste of time.
I prefer diversification when the money is already huge enough like $100k ++ then we could diversify to crypto and to other asset, diversification in alt for the most part, is just waste of time.
Overall, diversification has both advantages and disadvantages, it is not as perfect as we imagine . It can help us reduce risk but it can also reduce profit because not all coins have the same increase when the market is bullish .
