I choose to save bitcoin and cash. Because we dont know about the future. We must have two plan. So if one plan is not working we have one plan as backup. just in case should keep both.
We need cash at this stage in my country because cryptocurrencies are banned here and we are living here with disadvantages as we have to pay huge taxes on money related places and things. The crypto world has brought easiness for the whole world and is spreading all over the world, now I am waiting for the government to accept it after which I will keep for my children as well as I prefer crypto over cash.
