Its your Choice to invest in a project where human trust is needed. I can also put my money on a bank. Instead of investing in blockchain.
With btc there is no question or discussion if x person have keys to print free btc's. A 51% attack is needed for creating more btc's.
Its not possible for digital money to become global money if its not 100% trustless.
Why should the mayority choose trusted digital money if there are other better trustless solutions out there.
Sorry bud, but it's already global , there are buyers from Russia, South Korea, India, Indonesia, China , European countries , African countries , etc , more to come. You have to always trust in human bud, even in bitcoin, trust that there will always be human who will deem it valuable.
