What are the most promising cryptos to buy? How much % should you put into eth/btc and other cryptos?
HODL is the term used for long term holding and you are saying that your time period of investment is 6 months which is actually mid term trading not the longest. I won't suggest you to hold any coin straight for the 6 months long, either choose to hold for long term or simply move to short term trading with BTC and stable coin pair.
