If what you are saying is that Bitcoin is not the most suitable then why people are still believing on this compared to other altcoins?
Bitcoin is the best option to use as payment method , that is why you will believe on this or forget it forever,..
The fee paid for transaction using altcoin i s low, the speed is faster than bitcoin, do not try to make certain excuses that are not true, bitcoin is superior, we all know that, but not in making transaction because altcoin are better in that case.
