bitcoin is great for you as a lifetime asset. if you invest bitcoin on this day, and you save it for your assets. probably in old age, you will earn from your bitcoin. you do not need to work in old age. because you can already enjoy the bitcoin results that you save at a young age. it is a good idea for you so you do not have to work in your old age. maybe bitcoin prices will be very high and your money doubled. you will smile in old age to see bitcoin provides an unexpected income.
Bitcoin is great but I will not call it a lifetime asset, we do not know if bitcoin is going to have a value in the next 20 years, it is likely that it will and that the price for each bitcoin is going to be very high but a lot of things could go wrong during that time so the best thing is to hold bitcoin but be always ready to get out of it in the case you have to.
