Hello There!

At one time, I stopped being interested in the altcoin-markets because of the situation there. Famous projects were dropping their bags off to gullible investors to get even more money.
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?
The situation hasnt changed yet. Altcoin is still on bearish mode, which makes many altcoin down
So, if you wanna trade ERC-20 tokens, it would be risky. especially when you just take 'long' position
you still can get profit if you do 'short' trading. it sells high then buy again in low
or if you just wanna be long term holder, then you should buy Bitcoin only
if you want to do short-term trading with altcoin then you can use existing techniques. I personally am still in the stage of learning fibonnaci retracment techniques, there may be several other techniques. and don't use large funds if you are still learning how to trade in the short term because I personally use small but multiplying funds.
