general rule fo thumbs for many is that allocating very small share of the money to invest in altcoin just to convert it to bitcoin again for long term investment.
i think many have done that and they are gaining quite the money overtime and its such a good strategy too considering the money invested in bitcoin will almost always turns out to be great.
but I think altcoin investment not gonna be always that smooth sailing as expected.
so someone should make analysation first as usually. but after all it does indeed gives more profit than the other considering the volatile nature of altcoin in general.
therefore for altcoins I prefer to invest in altcoins that are close to bitcoin in ranking. for new altcoins maybe with small capital can be invested, considering that it has a big risk, so even if we lose, don't experience panic considering we still have major capital which can cover losses later. Above, we have mentioned several altcoins that are worth investing in, and we hope that the increase will exceed the increase in bitcoin, we are just trying to increase the risk higher, but basically stay safe. different from the new altcoins where we are just waiting for the pump and selling it, because if a dump occurs, it will be difficult to crawl back up
Personally, I wouldn't prefer converting my Bitcoins to altcoins probably because I believe in Bitcoin way more than any altcoin and I know that it is all because of Bitcoin if altcoins go up in price, if Bitcoin stays down, altcoins can't move up at all. But, if I had to do that for some reason, I would probably go with coins that are the most trusted ones after Bitcoin such as ETH, BNB, DOT, DASH, etc., because I know these won't deceive me.
Going with new projects and new tokens is risking all your capital, especially if you have converted your Bitcoins only to buy altcoins, you shouldn't buy ones that aren't trusted enough or can't provide you with significant gains when there is a bull run or even if there isn't a bull run.
