This is the problem with the Bitcoin enthusiasts - they think they can predict the future price with near certainty. You don’t think that rosy picture of BTC is held by thousands of others and already baked into the share price? “Highly unlikely” only describes Bitcoin’s potential as a store of value.
If your investing horizon is any amount of time, Bitcoin is not for you. Bitcoin is not an investment, it’s a pure speculation. As another comment perfectly summed it up, lottery tickets are not an investment.
