Introduce a bitcoin mining tool. As long as you install this app, you can mine bitcoins for free every day. It wastes your device power to mine bitcoins, so you use more mobile phones or computers to log in to the same account. The speed of mining bitcoins will be greatly increased, and there is also a offline function. As long as you recommend more people to mine bitcoins, the speed will also increase. This program has been verified to withdraw bitcoins, and the minimum withdrawal is 0.00001btc
https://cryptotabbrowser.com/21657369It is definitely a fraud. Cryptocurrency mining is really costly since it requires an expensive mining rig to be profitable and mining through your device's power is unrealistic. Offline function? I don't think so, it needs to operate 24/7 which's why it is costly. Lastly, there's no referral system when it comes to mining so don't waste your time and stop using that application it might leads to destroying your own device.
