I know what ACH is. If you need to move money quickly, you use a bank wire. If it doesn't matter if it takes a few days, or the payment is predictable well in advance, you can use ACH. The point is that ACH is not intended to be an instant transaction - so why are you comparing a 5 day ACH transfer to a 4 second cryptocurrencyofthemoment transfer?
That's totally putting aside the trivial issue that cryptocurrencyofthemoment can't actually be traded for 99%+ of the goods or services one would want to spend money on in the first place, without first paying the fee and waiting the time to convert it into an actual currency aceepted by actual businesses.
What are you arguing here? That I need to "get in on the ground floor" by buying some cryptocurrency now, lest I have to pay a premium when things go big?
Are you telling me that you can predict which cryptocurrency is going to be the standard in 10 years? Maybe I should buy some of each, just in case?
Are you telling me that in 10 years when cryptocurrencyof2028 (CC2028) is dominant, that I won't be able to trade $100 for some CC2028 and then use CC2028 to buy roughly $100 worth of goods or services? That I'll be locked out of that medium of exchange forever because I'm not buying buying buying today? That I'll be gnashing my teeth at my inability to spend my $100, wishing I could go back in time and buy some Dogecoin or whatever ended up winning?
Are you actually saying and believing these words?
Thanks, but I'll take my chances. I hope you make a lot of money off that money "that you're willing to lose" ...
