Plan for your children or future children by saving Bitcoin for them. Buying them bit by bit would be a great investment for the future of your kids. I am saying that you must have a new wallet for your kids so that when they come at the right age, you can give them that wallet and imagine how bright their future will be. You can hold bitcoin for their education, life plans, or whatever you think of.
I believe that if you start storing bitcoin for them now, a bright future is ahead of them
OP, you said it as if the price of Bitcoin will forever continue on the up trend. Investing in Bitcoin is like investing in any other business. Businesses do have their downtrend from time to time. If in doubt, you may want to find out from Mark Zukerberg or Bill Gates. I am one of the VERY few who believes that Bitcoin will not forever trend upwards in price. In fact, a time will come when other coins will go top it.
