I also have many reasons why i love bitcoin besides earning income. These includes
1.Bitcoin is like a bank thats never closed, this currency is moving and available 24/7.
2.Its decentralized, no need for any 3rd party to babysit your transaction and take a piece of it.
3.More people and places are starting to accept it, from coffee shops, to real estate owners, this is a currency gaining traction and it's gaining worldwide acceptance.
4.You dont have to physically carry it around.
