Yes, it's an major issue and transferring money Globally is big task and for some people the fees is unaffordable and they fail to send the money and in my opinion this process never tried to improve by the central entities.
Yes, at this point of time the Crypto is not effective if you are sending money through Crypto for direct spending because as you said the value of Cryptos are volatile and it can fall drastically and it's ineffective at this moment.
And yes, Blockchain is great tool for transferring the Cryptos and in my opinion as soon as we enter into the Global Crypto Sphere then we can use Cryptos as medium of exchange effectively. Transfer of Cryptos for direct spending is ineffective and it's not an effective choice for now.
At this moment i am not aware any of the projects and if any then that would be great because in my opinion this service can bring great change in Crypto and this phase can open great opportunity for mass adoption of Cryptos.
Wishing you an great day and stay blessed. 🙂
