Hi guys i will try to write a little handbook about how gain more value at cryptocoins world.

First question. Mining is worthy? 

GPU mining is not all worthy. You pay more at electricity that the cryptocoins you gain.

CPU mining is worthy only at passive version. I mean not to do cpu mining with your pc but make the others for you passively via JavaScript (mainly Monero mining)

Airdrops is worthy?

Airdrops gives you free cryptocoins as promotion. But the 99 % are useless without value. Only airdrops of exchange listed cryptocoins has value because you can exchange these coins with BITCOIN , Ethereum etc

Faucets are worthy?

Sure you can gain some bitcoins or Altcoins for free. You will never be rich with faucets but you gain for free cryptocoins

Altcoins are worthy?

Altcoins are like gambling. You may gain or loose much mi. Only etheret, litecoin, dashcoin, dogecoin, bitcoin cash, stellar are the most reliable.

Stablecoins are worthy?

The plupart of Stablecoins has price standared to dollar. The  price is exactly as the dollar.

And last of all bitcoin is worthy?

Bitcoin is a revolutionary. It is the nrw era. So it os worthy.
