Nobody knows the future. Just like any other investment, you have to take the risk and play the game. If you think spending $30k or more is too much, then lower it until you can feel safe even if you lost your money. Don't risk it all and do DCA to play it safer.
I personally just buy on a monthly basis without looking at the price and plan to exit a few years later. Design your own strategy and the risk you can take by yourself since you're the only one who knows your condition.
That's right, no one knows what will happen in the future. Late? I don't think so, because until now Bitcoin is still around and growing. Likewise with other currencies, it continues to grow, increase or decrease, even the output of new currencies continues. It's never too late as long as you want to learn, because investing also requires expertise, not just depositing your money and forgetting it, there are many things you need to consider when starting investing. As he said, trade money that you are prepared to lose or feel safe if you lose it. You say 1 or 2 BTC, that's a pretty big amount to invest. Think again, if you are not ready to lose money with that amount, then don't do it. You must be ready to lose whatever you invest, not expecting us to lose, but when it happens, we can accept it sincerely.
