But in the next 24-36 months, bitcoin is somewhere between 10k-50k. It simply has to be. The scale at which the entities getting involved now operate scale wise, bitcoin will be forced there. And 17 year olds that mined this useless Internet money will have their minds blown.
To be fair, you're taking a bet that e.g. the US government won't ban the use of Bitcoin in the US. Look at India and China, for example. Bans can be quite effective. If the US government banned Bitcoin tomorrow - not beyond the realm of possibility given the US Treasury Secretary's recent remarks and the difficulties regulators and the IRS will have addressing Bitcoin - it simply will not have the chance to grow to the size you want it to be.
I'm long Bitcoin too, but it's a gamble nonetheless.
