Everyone has earned a lot, as always, even if in denial, altcoins go down as Bitcoin price falls, most newbies sell their earnings for fiat which takes the price down and on the other hand we have the bch shills ready to fud.
It is very hard to distinguish between a reliable coin which desires to offer innovation and a future to itself and shitcoin's made to profit, while bitcoin was cheap it was easier for communities to locate scams and ponzi scheme like operation's yet now with the hype and the crypto vogue it became fairly harder to locate them since the amount of ICO's has raised dramaticaly, besides that we are also getting an amazing influx of token's which are even harder to check since they are easier to make.
Remember politicians, they talk a lot, promise a lot and end up without doing shit... It is exactly the same here just that they need better graphic designers, I believe such sites as FB,G,YT A.K.A Giants should check deeper before promoting ICO coins and tokens there is an amazing amount of them (a lot exist already) that actually are trustworthy projects with future yet it is known from the past that a lot of them might either take the money and run away, leave a backdoor in the smart contract or simply keep the fund's raised for themselves for these reasons one must take investments from a different perspective and not throw themselves at first ICO with few coins invested/ too good to be true promises or exagerated supply size since there is hundreds perhaps a couple thousand coins from which a bigger than expected number are actualy something.
