My age is 27 and i am with crypto for 3 years since i start and regularly i work with mobile or pc like 12-14 hours. But in this 3 years i took my glasses in first year just a little bit of power glass.  But after that in this two years also added more power in my eye glasses. Now i am worried about how much time can i stay with crypto. And in this digital working system where i can earn for long term i think i should focus on other business also for my health also for everyone who wants to stay with crypto and not for long time in a day!!
