This is a little tutorial how to make a few extra bucks with almost no effort.
You don't have any risk and this is not a scam. (I know, sounds scammy)
I will try to make this as simple as possible. If you are skeptically you can of course do your own research, but this is legit.
All you need is to own some Bitcoin.
Here are the steps:
Download the Byteball wallet from
https://byteball.org/#downloadInstall and open the wallet.
click on Chat -> Transition Bot -> Insert my address
Now send a tiny amount from a Bitcoin address where you control the private key to the address given by the chatbot. If you got your coins on an exchange you can use the electrum wallet for example (https://electrum.org/#home).
Once this transaction is confirmed, you have linked a Bitcoin address with your Byteball address.
Now the following happens:
Each fullmoon your Byteball address gets credited with an amount depending on the balance of your linked Bitcoin address. On the next distribution which is on July 9, 2017 at 04:07 UTC each BTC will yield you 62.5 MB. The current market price (https://bittrex.com/Market/Index?MarketName=BTC-GBYTE) is around 0.0003BTC/MB. So each Bitcoin on your linked Bitcoin address at that time will pay you ~1.8% interest. Your Bitcoins are safe, since all you did was making a small micropayment to link your account.
The linking process has only to be done once. So if you are a long term hodler you get payed interest every month on your Bitcoin without doing anything.
Not bad if you ask me.
