difference between blockchain and cryptocurrency, Block

In this world, the hard way is uphill.Because only in this way will we be happier.People's best girlfriends are solitude, fitness, reading and music. No gathering, no gossip.

Don't lose heart because of one dissatisfaction.The mountain has its peak, and the lake has its other shore. In the long road of life, everything turns around!Because only in this way will we be happier.

Be with people who encourage you to move forward, with people with the same three views, with people with interesting souls,Don't deny yourself because of temporary difficulties.
