I think that this is the best thing to do if you have a family and you want to secure your family. If you want to have a great future then you should save bitcoin for your children and you should do a lot of work before you reach to the point that you can relax and feel safe with your savings because if you will become greedy in spending money from bitcoin then the savings will not happen because the problem is from you.
I agree, even though I do want to take benefits of the profit from my investment in the future I think mostly my future children and family will make the most out of it specially the bitcoins I will earned and hold by that time. I'm afraid I'm at that stage where I wouldn't be able to travel and move much but as long as I see my plans succeed and my family happy then it wouldn't be a problem.
Why? You do not need to spend all time to work in Bitcoin and save Bitcoin for your children while you do not have any free time for relax and travel with your family in holiday. You should think trading or earn Bitcoin like a job, you still need to have relax time.
He can also earn bitcoin even on vacation as long as there is internet you can do signature campaign it wont eat all your time if you know how to manage your time. I sometimes go on vacation but still earn bitcoin.
