The main reason I'd like to explore them a bit is that PayPal has been getting greedy of late. One of my due diligence litmus tests when contemplating a new partner is to contact them, by email, by phone.
In the case of Transferwise, they're scoring 0 out of 2. They just didn't bother to get back to my mail, or call me back, in spite of their promise they would.
In addition, I came across a Transferwise query result link in Google that stated something along the lines of "Due to repeated bugs in our blah-blah funds transfer system, we've opted to do away with this system". When I clicked the link, I got a "404" in the Transferwise site.
That's 3 strikes.
I hear decent enough buzz about them, sure, but there's no way I'm going to chase up a company to please take my money. FT.
Bottom line, they've found a way to stretch out a few more years out of a system that, let's face it, is pretty antiquated. But I'm willing to wager you a dollar that they won't be around in 5 years.
Pay me in crypto, thanks
