I am extremely skeptical that it will only cost few cents. (I've sent and received BTC in early 2010s)
On ramp and off ramp to fiat will kill you - whether through transaction fees or through slippage.
Let's say I am in US with 10k USD cash and I want a family in Ukraine (let's say somewhere safeish like Lviv) to have that 10k USD in hand.
Crypto is going to be more expensive than Western Union/Transferwise/SEPA/regular bank transfer/courier through friends.
That is the problem with crypto transfers - sure most crypto coins can be transferred cheaply.
However that "cheapness" only works as long as you stay in crypto verse.
