I feel like im gambling by going all in one crypto like ETH and the drops are hitting me very hard with its high volatility compared to BTC
Both has very high volatility.
I'm pretty sure if you are saying gambling, then you must be doing something wrong when trading. Have you done any research and not jump into it blindly? Drop in trading is pretty normal hence it says very volatile.
I would prefer to spread your investment into 10 top coins on coinmarketcap instead of just putting it into singular coin as the title says. So, your investment won't become a disaster if one coin dumps in one moment.
ETH is a good investment, aside from bitcoin, I would recommend holding it along with bitcoin during this bear market. There may have been a rush on his part to invest and he did not have time to do extensive research before deciding, but ETH is a suitable investment option.
Once a bull market happens, bitcoin will go up in price and it will be the 2nd coin to go up in price after bitcoin and ETH is very good at creating new trends in the market, so I personally feel safe holding ETH.
If you hold another altcoin it is a concern but not with ETH. Portfolio diversification is good, but holding too many coins while the investment capital is not large enough will not bring you good returns.
