Adult children someday fly out of the nest. If I were you, I would go my own way; everyone should have their own way. Until you achieve significant results in Bitcoin, all your good intentions will do nothing for your brothers and have no value. People want to see proof; moreover, if you are now in a bad relationship and tell them to invest in bitcoin, which is a very risky asset, and if your ideas do not go the right way, you will quarrel with your brothers even more.
Let people decide their own fates so as not to blame you for the future.
I have had to read many suggestions and opinions of people about this issue am having but this git me think very hard knowing I wouldn't like or want anything that should worsen the situation either now or in the future more than it is right now. I can help to see them have it hard the way they are financially but I think based on this I just have to let my results speak for me and am sure that will in some way drag them to me rather than the other way I was about to go to them, and it will be easier for me to then introduce or talk about bitcoin to them after our relativeness issues must have been resolved.
Thanks alot to everyone for the contributions and advise.
