IF you want to earn Crypto without investment
You use
a. Faucet
b. Mining
c. PTC
d. Shortlinks

I don't really recommend PTC Shortlinks as I found that they take you to sites with malware and if you don't have a good antivirus to catch it. Your computer and laptop gets infected.

Which site do I use to get get tokens?
