I think according to me it is the best to invest in Property, cryptocurrencies comes with great risks but they are most volatile. Which according to the people's belief is a bad thing but I do think , it helps a great deal in trading , you can actually earn more than anything in cryptocurrencies .
If you want to just hold the money and are looking for an investment to grow over time marginally , go with property .
But if you happen to be a person who wants to trade and engage in investments of volatile nature go for the cryptocurrencies they are by far the best thing in the market.
