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 is 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 for making transactions with low fee and fast speed. .
Yes, altcoins such as Tron have better transaction speed and low fees compared to Bitcoin. Also, Bitcoins volatility recently create problems such as if I am buying Bitcoin using Fiat to send but Bitcoin value decreases in the meantime. The price fall sometimes has a huge difference for which transaction gets postponed in the case of Bitcoin.
Also, if we compare Bitcoin with fiat, I would say we still can't rely on Bitcoin completely for any transaction if there is an option for fiat which is cost-effective and easy. And the recent delay and fee structure make it tough to compare with fiat. But altcoins, as mentioned above, can be of great help it is based on the acceptance of the coin.
