Nope, don't go all in like that, i think it's really bad ideal for you to do that . Place all in your funds in it would make you broke.
Yeah, everyone should have backup(s). although bitcoin won't fail you, just in case. i'm like 60% in bitcoin, i have invested in several altcoins(top ones and few other interesting ones

) as well holding some fiat.
It's good to have a backup always, before I put all my savings on bitcoin when I started in crypto, with my salary and allowance sometimes since I know it will grow more in crypto than in banks, but if you'd already earn enough then better be safe, save.
