There is many ways to obtain and grow bitcoin. . .the best way is to get it like changelly or even blocktrade through steem here..but after you obtain...go forth in the exchanges like polo or bittrex or Liqui and place that bitcoin on brand new ICOs that are legit and watch The Power of Our Human Markets grow your Crypto...this is the best way other than mining..
ive gone from $20 to over $2k in two months. .
