Your #2 would be monumentally awful for the economy. The individual might like it if they can let their money just sit there and hold value, but if everybody can save like this, then there is very little incentive for anybody to ever lend out their money. If nobody wants to lend, then nobody can borrow either.
(Technically, the price of lending/borrowing, i.e. interest rates, would skyrocket until lenders were willing to lend, but then almost nobody would be able to afford to borrow anything unless they had something with the potential for monumental returns)
If nobody can borrow, then how does anybody start or expand a company? If starting and expanding companies gets massively more difficult, then who will employ that 30 year old in the first place? How would any new product or technology ever get created and distributed?
The Austrian theory is that this problem solves itself: 30 yr olds try to hide their money in "inflation-proof" non-fiat currencies for 50 years, and then when they cash out they get a crash course in Supply and Demand -- all these BTC flooding the market and no one producing anything for sale drives the (nominal, BTC) price of everything up, so those BTC don't actually buy much anymore, and people have to go back work to make things for each other.
