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!
investing all savings? its up to a person on how he/she will handle this kind of i should say a problem but for me if i have savings i only invest the half of it because the other half of my savings was this gonna be for my daily needs and for the things that i really need so that im not going to invest all my savings.
