Many people limit their profit by not taking the right actions but trust me every penny worth
Even if u have low budget to invest for your kids do it , and save it for more than 15-20 years
e.g if u put today 100$ on BTC to save for ur Kids future , when they are 20 years that 100$ will go up and down in hours as bitcoin will hit High price
That's quite a long time to hold Bitcoin, but it's worth it for most investors, especially those enthusiasts who have been holding Bitcoin for more than 10 years now. They continue to hold their Bitcoins despite the current price, envisioning a higher value similar to what you have envisioned.
