I agree, but doesn't increasing complexity of trading mean that there should be some tools for it?
It means actually. One good way is to try to reduce complexity and volatility. First good example was tether coin, which has been (and still) trying to avoid volatility by backing the asset with traditional currency USD. Right now is not the best time to buy it imo. Another reasonable way is face complexity and diversify your basket as much as possible with top crypto assets. However, it has its difficulties.
It's not easy to diversify a basket to even 6-8 assets. But anyway it's better than to do nothing. Do nothing aka HODL is like to choose one gun shot instead of burst of machine-gun fire. Take a look at the project CryptoIndex.io. And let me know if you find something similar. I find it really interesting.
