Okay, these are giant companies but they can't really push cryptocurrency forward. There are companies that will get involved and it will encourage a lot of people to start making use of cryptocurrency, just like Amazon. If Amazon starts accepting cryptocurrency I think a lot of their customers might decide to try out cryptocurrency, especially Bitcoin to see how it works and get to know everything about it and it might even attract more investors. But the way I see it, these people are never going to be part in crypto they would rather create their own and try to convince investors to take part in theirs. Imagine that there was nothing like altcoins and we have only Bitcoin and everyone was putting all these efforts towards Bitcoin alone… then it would have gotten far by now.
