As i write this article , the crypto market is heaving with trades and transactions the background processes that enable these to happen are whirring away.
In order for this process to work, computers / servers are needed to process a sum to finalise the action and complete the blockchain, every transaction has this and that's where mining comes in. You see each completed transaction has a fee attached to it and whoever completes this sum first gets paid a fee , there are thousands upon thousands of these being completed daily and by cloud mining you are joining in the fun.
for example: £3,000 invested into SHA-256 is currently giving £110 - 130 a week and that is for life..!
