hola, ¿existe en el foro algun tuto para hacer staking?, les diré lo que yo lo he estado haciendo a ver si es staking o no:
1) he estado minando con minergate con varias computadoras viejas, moneditas baratas, lo hago de a 100 monedas cada una
2) me meti en swiftdemand
3) de vez en cuando compro monedas con precio $0.00x

Esto es todo, Pienso que es una buena practica,  he aprendido mucho y no me cuesta nada, pues el costo de electricidad e internet en mi pais es practicamente $ 0, ademas tengo entendido que existen cosas como airdrops y otro termino que no me acuerdo. ¿cuales otras practicas aconsejan?

There are few ways to transfer funds from paypal to a BTC wallet and they aren´t cheap, since I don´t use P2P exchanges, I only will show some alternatives I have been using for awhile.

********* USD from paypal to a BTC wallet using VIRWOX (AKA THE DISGUSTING WAY) *********
It takes a lot of steps, at the end of the process they reward you with an insufferable 24% commision and they keep some money thanks to their "minimal" tradeable amount policy (which is brilliant if you are the Virwox owner)

********* USD from paypal to a BTC wallet using UPHOLD/AIRTM (fees are so close to virwox but hey! they use smoother web interfaces) *********
you have to use uphold and airtm accounts together, three pros: 1) paypal works with airtm and airtm works with uphold, 2) You can fund/withdraw fiat money from/to your bank account and crytocoins wallets, 3) You can create your own wallets within uphold.

Now the steps and the math:
1) SEND USD from paypal to airtm (fee 21.5% + 0.30)
2) SEND USD from airtm to uphold (fee 2.5% + 0.30)
3) within uphold, convert USD to BTC (fee 1.05%)
4) SEND BTC from your uphold wallet to an external wallet (Network fee 0.0007 BTC)

as you can see, both methods takes a lot of steps, they are relatively secure and high fees

There is other alternative but it is in development yet

Stop using paypal and use airtm because you can receive/send or fund/withdraw fiat money using a very long list of sources including your bank account and soon crytocoin wallets, this last part is what I waiting for, because in the next future I will receive all the USD payment from my customers in my airtm account, convert to BTC and send to my external wallets.

only one answer for your 4 questions: forget paypal, just use uphold or airtm.
