Do you think the situation has changed in the year 2020?

Is it safe to trade ERC-20 tokens and is it possible to earn something else?
Thats how the case has always been for alternate cryptocurrencies, they are mainly a disappointment. The only cryptocurrencies that dont disappoint are Bitcoin and all the top altcoins. There are lots of new projects that are being released every time and most of them at then end they fail. This is what is causing a lot of people to be giving up on all these new tokens.
Manipulations have always been and will be and this is not only in the crypto sphere. I really hope that erc-20 will move off the ground in 2020 but I prefer to trade bitcoin and ether.
I dont think there is going to be an end of manipulation in the market, as long as its a volatile token or coin, it will always be manipulated. Cryptocurrencies are mostly decentralized, there is no Central control unit, so people can do whatever they want to do.
