And the strong reason I stopped smoking was because my wife likes to nag me if I smoke at home because I have small children, and over time I decided to stop smoking. And previously I tried it several times but failed, and now I haven't smoked for more than 3 months and I hope I can do it forever because it has two extraordinary benefits. Health and can increase my investment.
Apart from the obvious economic and health benefits everybody is talking about, the fact that your wife can see it as something good too has also a great value. Many bitcoiners have problems at home because their relatives think that it is a scam and they are wasting their money, but in the case of the OP's wife, she can't complaint because it is obvious that his husband's decision is good compared to slowly killing himself.
Congratulations, btw. Keep up! be strong and don't give up. Your family will thank you in the future.
