The important thing to remember when you enter the cryptocurrency space is that invest what you can afford to lose. I would never recommend anyone to sell their property and invest in cryptocurrency.

The top 10 cryptocurrencies according to the market cap on CMC have a bright future ahead. As @avikz said Bitcoin and Ethereum have a bright future which is true but I would like to add BNB also on this list. Backed by the biggest crypto exchange it has a big ecosystem like Ethereum. In this space, it is always advised to do your own research as it is your money that you would be investing, so choose wisely rather than following recommendations from other.
