Exactly and this is why we need to be careful and analysis deep before picking altcoins. It is true that, we'll see most of altcoins will pump when bull run is underway even including shitcoins! Altcoins holding coins with no potentiality, can increase risk. That's why need to pick up man inly those, which are unfortunately down due to effect of bear run but have potentiality to pump in perfect time.
There is that much risk with those altcoins that we think have the potential but in reality, they don't have it. Picking them based on your research is dependent on how you will take all of those research that you've done. It's not just all about the profit that you'll get but also on how you see how the project is doing together through its developers.
Besides i might be good to pick up some top potential altcoins rather than adding lots of altcoins in portfolio
If you don't want to do that much then this is going to be your pick. Just rely on the top ones that have been strong all over these years and the ones that have proven their worth and have a good community. Those are just few reminders still you do you if it's about investing and altcoins.
