Need advice. Is it worth joining a crypto based startup at an early stage, keeping in view that the sector is too much under the financial regulatory authorities radar and business semantics can turn overnight?

I have an offer from an early stage company in crypto space and i need help in making a decision if is it worth or not. As the sector is highly under the regulatory radar so business is at risk whenever new regulations comes is as in case with the most fintech companies as well. Also do you think crypto does hold some real value and is here to stay for long?
