Bitcoin is going to dominate the world financial system in next 5 years. I sure the price can reach up to 10,000$/bitcoin in 5 years again. Bitcoin is the most important invention of last 500 years. You will see bitcoin's units not even mbtc will be traded equal to 1$. I would go for Bitcoin than Gold in modern era.
That's too early to tell mate, I mean we should do it one step at a time and your prediction is very unrealistic, we are not even $1,000 dollars and you are expecting $10,000 for the next 5 years, if you are that confident you can start buying now and risk more.
