From my perspective, bitcoin is an internet gold and as we know, we can not make small transactions, micro transactions with gold. Therefore, it is time for other cryptos to rise and become a good online payment for micro transactions
This. There is a good place in the crypto world right now for altcoins, many of which (DOGE comes to mind but there are many others that can fill the need) can transact small amounts for a very reasonable fee (much lower than traditional CC transactions that are constantly accepted as the price of doing business for convenience stores, etc). All we need is for large-transaction merchants to deal in Bitcoin with the possible addition of smaller cap cryptos, and small-transaction merchants to embrace a range of the more popular small-cap cryptos. Would I gladly pay a DOGE in fees to buy a soda? Sure. Would I pay the equivilant of USD$20 to make my soda purchase happen fast in BTC? No way.
There is a symbiotic relationship between BTC, the larger altcoins, and the smaller altcoins. Certainly, not all coins in circulation today have a future, but there is a place for a number of cryptocurrencies in the financial world of the future.
