Dear All,
one of my friends have 45 BTC in his pocket.(which was bought 5 years ago).
Need expertise advice how to use them effectively??
Help a friend out. Give me a bitcoin. Just kidding.
A good way to expand your bitcoin collection is to invest in alt coins. They'll pay you back your bitcoin if the ICO fails. Another would be investing in mining rigs. Buy more mining rigs with that amount of bitcoins and you can expand your army by tenfold. And to earn more, do it the old fashioned way, trade and hold.
