I think student shouldn't spend many times and invest for crypto.
You should focus for study.
Trust me!
Why not? Student while work in crypto world are smart decision that you should do if you can do that.
Research about the crypto are giving an information about the blockchain technology, crypto currency on how it works and what the benefits you can get from here.
4 hours to spend time for crypto everyday is enough for me to have an information and do your work with it like bounty participant.
Work with crypto like bounty campaign will helps you to earn money for your daily needs or tuition fees. Also it will help you to expand your knowledge about the modern world with a blockchain technology and crypto currency.
