Doesn't need long complicated answers - just a simple question:
Do you invest
1. mainly on price/the market trends
2. mainly on the underlying usefulness of the token/NFT
3. pretty even split of the two.

I often trade on the trend for short term investments. The altcoins I trade in the short term like ADA, TRX, XRP which are more affordable. setting a profit target is the most important for me, and I will hold the coin for a long time if it doesn't reach the profit target I set.
