Re: I am pretty confident we are the new wealthy elite, gentlemen.
It's nice to be able to think that in the next 10 years, the newcomers to this thread will view us too as elite. 
Probably, well the only risks for me:- most governments banning BTC (not likely, if there is too much money in cryptos, I doubt governments ban it, would rather could tax it)
- an altcoin overtaking BTC, this is the biggest risk IMO, I hope BTC constantly improves so that it can be able to keep the lead
otherwise, 10 years from now, it is not difficult to see a price of 100 000 or above.
This is a personal opinion and not a recommendation to buy.
Very much the chance of bitcoin can reach 100k if it's 10 years away, but I think, ideally bitcoin is no more than 30% of the total market cap, if bitcoin too dominate it can kill other coins and just wait time then users will get bored and eventually leave bitcoin.
