1. Don't invest in crypto if you can't afford the loss.
2. Don't put your eggs in one basket.
Do not invest in pump and dump shit coins
How exactly? Ust was reason for luna's downfall. On its own Luna was/is thriving dapp platform.
Tbh luna was just another pump and dump shitcoin. What unique feature luna had over eth for example? I can't think of any. Then why did it exist in the first place? There are thousands of alts around and only a few of them are unique and decentralized. Monero for example is still the best anonymous coin and every other competitor is just a failure.
I guess no one saw it coming, specially from Luna CEO and founder. But as it fall from grace, now we understand that it is shitcoins anyway and maybe the intention from the very beginning is for pure pump and dump. So no, they can't be compare to ETH and all any other competition right now is just a copy cat version. So we should really be putting money that we can afford to lose as the risk is high for this kind of projects.
