At the beginning of the cryptocurrency boom, Bitcoin seemed to be the unquestioned leader. Up until early this year, Bitcoin accounted for the vast majority of the industry’s market capitalization; then, in a span of just weeks, Ethereum, Ripple, and other currencies rushed to catch up. While Bitcoin is still in the lead, the rapid turnover in the industry has some analysts debating if cryptocurrencies are actually currencies. Some are predicting that even bigger changes could be ahead. Among them? The idea that cryptocurrencies could come to replace cash entirely.
Of course, if one or more digital currencies does end up "making it" in the real world in this way, it's likely that investors in the cryptocurrency will see great rewards for their early adoption. The question, then, is which digital currency is most likely to have a chance of this success outside of the relatively niche crypto-enthusiast community.
Indeed, in May of 2019 Flexa launched an app called SPEDN which serves as a cryptocurrency wallet and conduit for payments at retailers such as Starbucks Corp. In this way, bitcoin has outpaced all other digital currencies currently on offer, making it in the most usable digital currency in the mainstream business world at this point, at least when it comes to payments.
Going by the foregoing, I can say that revolution towards outright overthrow of fiat regime has begun already, the future is with crypto.
