Most the favourite projects I have in mind to buy have already lose 80% to 90% of their value, if you are in my shoe would you start buying? I did try to buy piece by piece like 20$ to 30$ range but I still don't know if I am doing the right thing... I have these projects in mind

1. Theta
2. Sad to
3. Lukso
4. Mina Protocol
5. Layer zero
6. 0x
7. Woo Network

But looking for good entry per dollar
