We give the coin value. There are developers who take how much money they need while there are some that are money grabbing shills that destroy the community and the trust.. but you must filter them. If you look at history you will see centralization always results in corruption, we are supporting decentralization and this is just the start. What gives USD paper value? People give it value. What if instead of USD paper everyone started accepting Crypto? We could change the world and that's the long term outlook, right now everyone is still researching and developing to create Cryptos with world changing potential. I could write a whole essay on the history of centralization and the consequences along with the change that needs to move society forward towards equality. Find a decentralized Crypto that serves a purpose you believe in, if you and enough people support it then it will have value and that value will probably increase. Find something you believe in, most people put money just to make profit but don't understand the purpose of Crypto at its' core. Serve that purpose and you will profit while also supporting mankind in the right direction. I know Crypto has turned into a gambling game with many developers shilling it but there are still purists who see it's potential to change the world for the better.
