You may have a point but I do not agree when you say that HODL is not advisable. HODL is proven effective by so many experienced crypto fanatics, even expert traders. So I guess HODL is advisable to a certain extent. To demonstrate it to you the importance of HODL, you may just take a look at the previous year. Take a look at Bitcoin, Ethereum, LiteCoin, and other solid coins.

If you are not very confident with day trading, just HODL.
