Are you out of your mind? why would you sell all your properties just to invest in cryptocurrency? I mean you are right that today is good time to buy/invest in cryptocurrencies because the price had dropped significantly but selling your valuable things just to invest it in cryptocurrency is the dumbest way to invest even if it can give you a great amount of profit in the future. Cryptocurrencies are unpredictable, it doesn't mean that when the price crashes it will no longer drop so you are still risking your money even it is a good time to buy. Much better if you only invest what you can right now.
