Well I think you have already started but you just have to take your time to learn more because in the bounty section many forum members don't really care about what they actually do, what really matters is just keep working on these bounty campaigns to earn which like you said are no longer that profitable as it used to be so I have heard. But that being said if you still want to honestly learn about bitcoin there are so many easy ways to go about but firstly it all involved reading and maybe some vital video on YouTube that breaks the basics about bitcoin.
Nothing in this world that's ever too late as far as there's life, there's hope. You can start again especially when you have the knowledge before. That means you are not starting from the scratch, you are starting from some where. you are starting with the experience that you have gotten. So I don't think it's too late. successful people don't think like that. They said the broken leg of a lion is not the end of its life. We should not have this habit of suddenly loosing of hope. we should always have strong hope that one day it shall be well.
Of course it's not too late for you to learn about BTC on this forum, but I don't think there's any harm in joining the bounty if you're interested, because you can potentially benefit from the bounty while also learning about BTC on this forum. and op I also like participating in bounties and honestly by following bounties I am more enthusiastic about being on this forum. and there are so many good replies from our friends, I hope you are satisfied with the answers given by members of this forum.
Exactly, I also have the same perspective as you. one should try to be proactive all the time. when you are already engaged in one activity, that doesn't mean you can not do or be making way out for another opportunity. When you are in the forum you can as well be participating in the bounty. Because they said no knowledge is lost. And not only that. You can be earning and be acquiring knowledge simultaneously. The both are very important.
