I just stumbled across Stellar today and it looks very promising. I'm working on a new personal project idea and was searching for a way to build a Venmo-like feature into my app when I discovered Stellar as a possible solution. My question is: is Stellar a viable solution for long-term use in this regard if my app takes off and becomes popular? I'd hate to have to move/migrate everything down the road.
I'd like to have both the sending/receiving of money (primarily USD), along with the possibility of my users receiving a card in the mail, similar to Venmo, or to be able to use with existing digital wallets (Apple Pay and/or Google Pay).
EDIT: To clarify my question, I'm researching how I can integrate these Venmo-like features into my app and asking if Stellar is a good, long-term solution. I'm a self-taught developer and still learning so I've been researching how to build this and on top of this, I've always been hesitant with decentralized payment systems such as bitcoin. I'm mostly worried about the future. I'd hate to have to have things break down the road if Stellar no longer functions or whatnot. I hope this helps clarify my questions/concerns.
