I have 12 Bitcoins. I am not a whale. I started about 6 months ago with 0.01 Bitcoins and $1000. I turned it into 12 Bitcoins so far and am pretty proud to say the least.

My question is, what do I do now?

As far as I can see, I have 4 options;

1) Hold the Bitcoin

2) Invest in altcoins and leave a little in Bitcoin

3) Fund a project and start my own cryptocurrency that solves a problem that current currencies face (scalability, Tx fees etc.). With the funds, I would be able to assemble a team, start a marketing campaign, get listed on exchanges etc. I am also a programmer which helps.

4) Convert it to fiat (probably the dumbest idea)

Edit: I should also add, I dropped out of school and have all the time in the world so can fully commit to any idea. I will earn my living of cryptocurrencies.

A few people have asked how I made my money so, if you are interested, here is a short summary:

Initially, I put it all into Bitcoin during the massive FUD of the fork around June when Bitcoin dipped to $1,900. Then I put half my money into NEO before all of the hype at around $12 and cashed out at $40. Then I invested in a couple ICO's and turned a pretty good profit of off the hype. After that, I got back in on NEO as soon as China announced the regulations regarding ICO's and rode the wave back from around $20 to $40 (I can't quite remember). Then, I rode the hype of Ethereum Dark, eBitcoin and a few other airdrop scams. Finally, I got in on Wincoin before it got to coinmarketcap and turned a 20x profit.
