Why I prefer ALTCOINS vs BTC for next couple months - My logic

Here's my logic

During next bull run, Bitcoin can go up 3-4x.
Good alts can go up 5-10x.

Even if Bitcoin increases faster in price at the beginning of the bull run, alts usually catch up and overtake Bitcoin at the end of the bull run.

Considering I want to hold and just wait.
I do not want to try to time the best time to switch Bitcoin for alts.

Let's say my objective is to reach $20,000 and I'm at $7,500 now. I just have to 3x my money before selling out.

Doesn't it make sense to just buy ALTS at a good price and wait until I reach 20k$ to sell?

I feel like chances are higher to reach my objective with alts vs Bitcoin. No matter how long it takes.

I'll reach my objective for sure with alts.
It's not a certainty with Bitcoin, or it'll take longer.

What do you think?
