You can investment your money in land, house, gold, silver, stock markets, fixed deposits & savings in banks, start some business or invest in some business (like restaurant, hotels etc..)
Actually Bitcoin and crypto currencies are not required/unwanted

Investing in land, houses, gold and silver or even starting your own business are all good options, investing in the stock market or putting your money in a bank is not really a good idea, some people here in the forum are against the idea of banks and if you give them your money you are just feeding them and making the system that you do not like even stronger which is one reason to invest in bitcoin instead.
