So far there are no signal sites or groups regarding exact coin potential analysis, mostly paid news or PR for shillings. You have to research independently.
The altcoins announcements board is now somewhat conducive with honest discussions on the 1st page. You can try to find good altcoins there.
I know nobody cant predicte where price will go in next few months, or years. But for what reason Cardano, Polkadot, or Solana is coin with good potetial? What make this coins good coin in crypto world?
I mean what coin must have to be good coin with some great potential?
A good coin has a good background too. That's why they deserve to be held for a long time (not as fast as 10 to 50x the next month pumping, then dumping) because they thrive healthily.
