Meanwhile in spain: Unemployed, barely can pay bills, my pet is sick to boot. On top of that: I learned about Bitcoin back in 2009 but didn't invest because it was always linked to criminal activity so didn't look into it, as a result, I see it on mainstream news 4 years later about how it went to 700 dollar a coin. Thank you Bitcoin for making me suicidal for life.
Sorry to hear about your pet. There is a reason the Buddha said "Life is suffering". All these things will come to pass, your health, your wealth, your pain, your poverty, etc.
(I'm not religious mind you, but think there is a lot of wisdom in ancient writings.)
So, instead of looking at the past (e.g. chances missed), or worrying about the future, while you are here just be a living example of what you wish others to be. The rest is all transient and in the end, doesn't matter.
So, for example, when you see truth (e.g. Bitcoin in 2009), no matter how it is used, if you see it containing good, then go to it. There will always be "bad" here.
And suicide, is rather like starting the game all over again, so be careful of your actions. Most people only seem to rise up and be happy through suffering, if that is any consolation.
And BTW - you are still an early adopter...
