Now, back to the altcoins problem, the fee for ETH is gradually spiking to 1.5 $ and we know the problem of scalability of ETH, what do you think will happen if only 1% of coffees would be sold via ETH?
Not to mention the size of the chain.
No blockchain would ever be able to accommodate the big four fast food sellers even with 1% of their sells and keep low fees.
LN....
You are saying something I have been suspecting all along and even I had a post or two on the subject. The problem of scalability is inherent to ANY blockchain. The result seems to be devastating: no cryptocurrency can successfully reach high adoption.
Do you think we really have to settle for off-chain solutions in a long run? Then what do we really need bitcoin for, when we already have perfect off-chains payment methods (visa, mastercard,...) ?
