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

The difference investing from crypto is that no government has control over your funds. Since most cryptos are decentralized, government has nothing to do from what you have. I woukd rather invest in crypto since this might probably be the future, knowing that more and more are coming to know and discover it. The possibility of gaining more profit is greater than the traditional way of investment. I actually have investment on that kind of means but I don't wabt to miss what this crypto might bring.
