I agree, owning more bitcoins or less bitcoins doesn't matter because we can accumulate over time. The important thing that we need to care about is profit, because when investing, our goal must be profit. If you have few bitcoins, but you can hold them for a long time, sometimes it will generate bigger profits even for people who own a lot of bitcoins for short term investment.
I don't have too many bitcoins, and I am still accumulating, but my luck is buying bitcoins is very cheap, even if I sell now, I will still make a profit. But I decided only to sell when they hit $100k or more.
If I have more than 1 bitcoin in my pocket will not be long term holding and looking opportunity how to earn profit consistency every day, bitcoin can't stable and guarantee will reach higher price until $100,000 based on many people speculation. I just want to earn profit with bitcoin opportunity drop and up every day.
Better earn little profit consistency every day than expected higher price from Bitcoin and waiting more than several years and we miss opportunity for selling bitcoin on higher price, maybe when bitcoin reached all time high above $64,000 many people have huge expectation will reach above $100,000 for sell it, but lately bitcoin have going drop right now under $23,000.
What you are talking about is trading and trading also doesn't need more than 1 bitcoin to begin. If you feel you have knowledge that can profit from trading then you can even start with $100. People like to hold because they don't have too much knowledge about trading or don't have the time and holding becomes easier. Trading or holding both can make a profit and the profit is more or less up to you, it has nothing to do with long term or short term.
