Diversify your investments by allocating your money into different investment mechanisms available.

While investing in bitcoin may be profitable due to its high volatility, there is always that possibility that the market may crash and its price may significantly decrease without any given notice. I do suggest that you keep the profits and re-invest your initial $5,000 until it profits again.

I also think it's ideal if you invest your money into stocks and bank notes. Focus always on long-term in order to at least maximize your profits. I learned this by experience where I failed to invest into stocks and its price suddenly increased after a few years.
