IBM is announcing today at Sibos 2017 the fruits of a partnership with Blockchain startup Stellar in which it successfully remitted real transactions using the company's custom cryptocurrency, lumens. I just bought 10K in Stellar and it is up 49% on Poloniex as I am writing.
The proposed use case; Stellar's lumen serves to digitally connect fiat currencies, allowing for exchange in seconds without the consumer or buyer ever dealing with the cryptocurrency exchange.
If you haven't heard of Stellar you are now behind the 8 ball. Learn fast.
