Crypto are making people greedy
Were people not greedy before crypto came to existence?
Miners don't care if they are consuming energy(electricity=water, E-waste = diseases/toxic..) in a bad way that can affect directly people, especially those in poor areas...
So you expect them to do what? Stop mining and sell away their gear? It will be their loss of the method of making money right away.
Investors don't care if you are investing the wealth that you worked for years to gather, And none will talk if it is a just a market where making right decision based on analytics and studies related to such or such crypto will definitely get you the reward that you deserve, Instead Pump-and-dump is what take place to solve the puzzle.
Seems like you have been scammed by a pump-and-dump group and you are venting out your rant here. Sorry but such groups exist in every sector of speculative market. If you think these are new and because of crypto then you are mistaken. You should read more about HYIP/MLM and such schemes and how Ponzi was started from Wikipedia.
Scamers and those are the worst, they use your own value of trust against you. Thing that make you question everything.
Everyday is a fight between legit users and scammers. You have to learn to deal with it and be smart to avoid them.
And in the other hand compared with the profits, donations can be considered null.
Donations in crypto is a voluntary choice. It is foolish to think that someone will just keep donating everyday because they are earning well.
