You have a good enough understanding to know there are thousands of crypto currencies. The popular Helium had thousands of miners but the group of 4-5 owners of the coin decided to screw all the miners, thus it became a scam coin - people still hang on to it.
There is only one rule in investing. Buy the best. In business it is winner take all.
In crypto currency investing there is one asset which is BTC.
There are only 5-6 crypto’s “safe” to invest in. They are ranked by valuations. BTC, ETH, SOL are the only three of the six that I would buy.
I am 99.7% of my 260K in BTC. I am free and clear with a profit in that 260K. I have made over 500K starting with a half dozen GPUs on a mining rig in 2017. Other than the valuation of the BTC, my boys both have a BTC from me.
The only true cryptocurrency inverstment is the BTC or the BTC ETF. At the moment the ETFs have the opportunity to grow at a rate higher than holding actual BTC, but I will hold my BTC.
BTC isn’t a unicorn-fiat, it is a Ferrari.
