NEVER go all in ever in something, whatever that is. Use maximum 30%-40% of your savings. It is the first rule of economics. Your idea of investing in cryptos is correct and many encourage it but put only a certain amount in it. Diversity in your portfolio is absolutely necessary!
This is really a very good approach. Investing all of your savings and that too in a one go is not a good idea actually. You should invest your money while thinking very much careful about what all you are planning to do. Investing all your money is a huge risk and you should not go for it at the first time. You need to have some money in your pocket so that you can use it at the time of need.
