Let's be frank OP you'll definitely invest in Bitcoin if given such opportunity to do so because everyone wants incredibly amazing return in their investments and that is one thing crypto does and that is why most people dive into the space and industry and it's begining to thrive.
I personally will invest 50% of the money in Bitcoin and the other 25% in Ethereum and with this two, I wouldn't have to bother so much and the the other $25 to seek other promising alt coins but will be doing the last very carefully

Let me answer this questions sequentially with the few knowledge I have and I hope I help some few persons too
Firstly, people shouldn't relates demo accounts to that of the real account because the demo account is just an account with merely virtual funds which the trader knows that he has nothing to lose from his end  and with so doing, there are possibilities of trading with comfort and focus, but when one starts trading with real account with has to do with real money from ones pocket, then there are usually great zeal to make profit at all cost and I leads to over leveraging and possible blowing of trading account.
People still start making losses on real accounts after long time trading demo successfully because the mindset has been changed and people wound to make huge profit in tye shortest possible time.

Definitely people and government will join the moving train and one thing is certain that government will never take down Bitcoin but rather join us in the future.
I'm very new over here and hope I'm welcomed.
