Indeed, very many platforms today are eager to develop digital currencies. I think, this is inseparable from the success of Bitcoin in the digital world. Facebok, Telegram, and Signal have very many users. This makes it very easy for them to make the coin rise. Especially now that Facebook has developed an ads platform. This is a new thing for Facebook.
If many of them decide to enter the market today and they each create their own coin, which means we will be having like 1 million coins in the market, then how do you get to choose which one to invest in? Because researching on projects is not easy, and for you to start picking them one after the other. I really thing they have to work together and should have partnered with a coin, maybe Ethereum.
