I would rather keep cash for my children rather than Bitcoins. Because, who knows? Maybe my child wont be interested in Bitcoin and then I would waste my time hoarding Bitcoins he/she wont use and because I was saving Bitcoins I would not have any cash. You have to first get your child interested and make sure it will use it so it wont 'spoil'.

Personally I like this kind of thinking about saving money for a long term investment. It is really a good idea to have the cryptocurrencies mentality and why not to inhert it to whom comes next. But are you sure that Bitcoin (or any other crypto) will lasts until your children are born. The studies shows that crypto in general will disappear in few years (they do not know when exactly) but why not start saving for a long term but if it is down you should know when to sell.

This is why we are on this forum because we do really wish to get some huge decent profits or money on bitcoin or even on altcoins which we can pass on our family or loved ones once we passed on this world.It is really worth to save up either bitcoin or some altcoins but yet its not really guarantee that it would last but somehow we can able to see the possibilities.

I think there is nothing wrong with that. In fact, I think, every savings whether in fiat cash or crypto currency like BTC  is a good decision. I'm also planning that in near future for my daughter. It's better if you will save in different crypto currency, not just BTC, to maximize your savings potential. Also, don't save  your all your money in BTC, always set aside for fiat cash in banks.

I am also setting aside an emergency Bitcoin fund that will most likely go to my future kids.  I don't have any at the moment but hopefully that will change soon.

Bitcoin is an excellent investment and I am sure the price will sky rocket in the coming years. 

I think investing in bitcoin as a stock for children is very wise idea. Because, investment we do goes without any party intervention and privacy is very awake. And bitcoin values continue to increase over time.

i will invest in property or gold than in bitcoin. because i dont know when bitcoin still exist.
in property or gold, every year the value will increase. and they have form.
in our country bitcoin not accepted and i dont it can be invest for long time or not. except the government give clarity of bitcoin

While you said that there are different types of investment that you can do for your children and there will be strong legal evidence to prove it and nobody can grab what fit in with you as lawful record.I feel it as being a good idea to make expense for kids in btc but kids these day are internet savy i really hope they'll discover it fast and if you child is too small to understand about btc its better you save the documents as document wallet and keep it secure in a bank locker or some secure lockers in your house however, you write down a will record declaring your possession and hands it to a person trust worthy if some thing happen to you all of your cash goes to your child and save them in paper wallet when its time your child will comprehend the value of btc and will have a safe education and future.

I would probably save at least 1-2 bitcoin for my children each, put it in a hard wallet and put it in a safety deposit box.
They can access to it for 10-20 years hoping that bitcoin still exists. 

I think it's a good idea, saving some bitcoins for the child's future.
I also want to be like that in the future. When children want school or other purposes just use bitcoin.
