Hello friends this system is quite simple and practical, you should only install telegram (on the PC or on your smartphone), then click on each of the following links:
To win DOGECOIN: https://t.me/DOGEClickBot?start=cSb0
To win LITECOIN: https://t.me/LTCClickBot?start=6al3
and to win BITCOIN CASH: https://t.me/BCHClickBot?start=oILf
Once you click on each link, you must press the word "start". These bots are super simple to use, you just have to click on the "visit" menu, wait 10 seconds for each advertisement and that's it, you'll have the amount of each advertising credited in your balance.
Finally you need a wallet for each type of currency, and ready, in what you reach the minimum withdrawal (the minimum is very low, you can withdraw just in a day) the bot will proceed to make the payment and in less than what you think you will already have it in your personal purse !!!
They are paying and they are 100% operative.
