In my opinion, it would be a bad idea to invest money intended for an important purpose in crypto. Promising crypto might be, its market is not that stable and you might end up losing your money. I would suggest you invest only money that you can afford to lose. This way you will not be pressured to sell for a loss if the price sways or fluctuates.
Exactly. Rule #1 of crypto has always been: "don't invest more than you can afford to lose". Crypto is a massively risky investment, profit is just as guaranteed as losses are. Don't think that crypto will give you free profits, because you WILL be dissapointed.
Don't overinvest otherwise you will lose sleep, you will be looking at the charts every day, you will be stressed, and most importantly you will make bad decisions based on emotions/stress and lose money because of it.
