It will be very important as usual to make good selections of our coins and while Bitcoin is looking very bullish right now, holding some Altcoins is very important because in a bull run, Altcoins are frequently outperforming Bitcoin because of new technology and innovation.
Here are my selections:
3# DOGECOIN
Dogecoin is an original coin and has been around for a very long time. Dogecoin is very famous because of Doge and it will always attract some people to buy it.
Compared to copies, like Shiba Inu or Elon Doge, Dogecoin will always be an original coin, not a cheap copy.
Dogecoin can be promoted easily because it's a timeless coin.
Doge coin happens to be my fav amongst all altcoins I have come across I'm recent times, because it has a very good potential of good volatility that will definitely profit it's investors in few years to come, this was Sean few years back immediately after it's much where it did above 10x in three days, early buyers were really profitable as a result.
Other altcoins just like you did mentioned could as well have good and wonderful potential for the nearest future but I personally prefer doge coin as I'm already used to it's eco system and understand it's dynamics to some extent, mind you I don't trade doge I only hodl, that has been my pattern to almost all crypto I ever invested in.
