[connexus]

I will start buy and sell business online accepting payments in bitcoin.

[dserrano11]

i will try looking for it's source for sometime, if i don't find anything then exchange it to usd and withdraw to a bank account.

[LowlandGorilla.]

Since I got the 50BTC for free, I would play with it on the Bitcoin markets.

[Whateney]

Definitely look into investing, maybe in bitcoin, maybe elsewhere

Would house flipping be considered a good investment?

[Snipe85]

I'd be so happy that i'd have to get drunk or drugged to calm myself.
And then I'd probably try to trace the transaction and know something about the sender before I start spending his money

Invest in Etherum

[sartorpc]

I don't know, but keep at least part of it.
