Ethereum and its competitors will be used to tokenize assets, and it may be easier to buy real estate in the future."
This reminds me of some altcoin projects I've followed in the past. They do similar things but in the end, failed. Some of them even run away and scam their users. Not really sure how to feel about tokenized assets, especially if most of them are overseas. Most smart contracts are hard to understand/verify and prone to hack too. I'd rather not buy them and stick with buying Bitcoin if an investment is my goal.
Here the problem is more in the legislation, and if something is tokenized, then most likely there will be additional protection methods that will not allow selling tokens from any wallet. Trading can be decentralized, but for this you will need to be registered on a centralized service.
And there are always risks in investing, but simple exchange smart contracts are difficult to hack.
