So true, we might be sacrificing today but it will all be worth it soon if we succeed with our investment regardless if its in crypto, real estate etc.

You can invest from your savings but not totally the whole part of it as you are not sure yet if you will make profits or the vice versa. If you'll lose, you still have some left for your own necessities.

Indeed, dont go all in because you'll never know what lies ahead. Its a must to still have savings in case there's an emergency. Just invest a part of your savings so you have something to count on in the future when its time to retire.
