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.
having some different kind of personality , are may having a your own decision and also your strategy on how you are able to handle this kind of situation for example this is what you are able to take for invest all your savings for this is may depends on the person that are trying to take that for.
