Bitcoin which code is only one page long had a bug, Ethereum got hacked 2 times, and you guys think Raiblocks which is on the market for less than 4 months is secure enough to trust 3 or 4 billion of your money to it...? It will get tested. Dont worry. And if it fails it goes to 0 , if it succeeds if will be a trillion dollars worth. There is no hush. if someone tells you to buy now or you miss the train , that person is lying to you. now it 3 billion marketcap. If Raiblocks can keep its promise of being secure it will be worth a few trillion. If you fomo and want to get in now , then you will just be the test subject.
your decision. And yes it is pretty centralised.
