well actually any that you find best suitable for you needs or most convenient. that's the point of bitcoins

Pink Floyd
Nirvana
The Beatles
The Libertines
Radiohead

i'm not a big fan of this idea. what will people do with their time? most of the life makes sense when we know it's going to end sooner or later. that's why we try to achieve smth because our time here is limited. the only positive way to use it for humanity will be space explorations. some day people will have to make these travels to other ends of the galaxies and immortality might come in handy for those who carry out the research

as i child i used to spend all of my summer holidays in front the computer and now i think what a waste it was. you should find something that connects you to the reality, friends, hobbies, food, travelling - in other words other addiction that doesn't affect you but helps you gain something on the contrary. just stay strong and keep away from the computer

huh it's kinda natural. not all whom we like can like us back and vice versa. you just have some pride and keep going, it's not the end of the world really (even when it seems so)

i try to focus on some pleasant things for me, do what i like to do and not what i have to. or think about people who are in worse state than me (it sometimes helps). and i like how this video puts it nicely https://www.youtube.com/watch?v=-kfUE41-JFw kinda gives you a bit different angle to look at yourself
