My personal opinion, i think to invest your money will be good option but only in real estate nothing else because property prices will rise every year.
Nothing rises every year, not gold, or stocks, or real state or even bitcoin, that is the kind of thinking of those that are left holding the bag and getting the losses at the end, if a market is bullish then take the opportunity to make money but at some point you need to cash out.
Bitcoin may be an exception to this rule, at least as of yet
For the first few years it was worth almost nothing, no one knew about it save for a few committed early adopters, who were stubbornly mining the first thousands of bitcoins with their decrepit computers in the basement. Then Bitcoin got some traction, and price grew a few dozen times (we will not see such things happen with any established asset out there unless something catastrophic should happen, e.g. a perfect Black swan event). After that, Bitcoin got publicity and its price went vertically up in just 2-3 months. It collapsed later, though it had been spiraling down for well over a year. But the adoption is still tiny, and if it should increase in the nearest future, there is no reason to think that the price might not increase exponentially again
