Just like me you also missed your chance to bag some cheap Ethereum, buying other coins isn't a bad idea if you ask me though, cause I the crypto space it's always good to diversify your portfolio, it's good to have other coins but just remember to make sure bitcoin has the highest share, cause bitcoin sets the trend for other coins, altcoin won't pump if bitcoin doesn't make any move upward, also buy reputable coins not shitcoins.
In my case I choose to invest in altcoins because the price of bitcoin for me is too costly and I admit that I can't afford to have my 1 bitcoin but so far investing in altcoins was also worth it. I'd still wanted and yeah my ultimate dream is to have even a 1 BTC in my wallet but it seems that it would take for a long time before I can get it. There are also many altcoins today that doing great in the market but of course all we have to do is to make our own research and see what altcoins have a great future ahead.
