Investing your hard earn money on cryptocurrency is not really a wise decision to make. We all know cryptocurrency trading is at high risks and can't be dependable. What I would suggest is keep 50% in cryptocurrency and don't act too greedy not to take profit. And the rest keep it in a bank this will be balancing your risk in half way instead of investing all in cryptocurrency.
Buying cryptocurrency is not always the same. You can buy Bitcoin which IMO is a great idea. If you think it's not you should get in touch with all those thousands of people who bought Bitcoin before december 2017. They should have a thing or two to say to you.
The other part of advice is good you can invest 50% but that doesn't make you safe. If you're trying to buy a house losing 50% will make you almost as miserable as losing it all because you won't be able to buy it either way.
