Ok, on investing, most of you here post old-school philosophy. Which I agree with - safe stuff for conservative investment
Crytos & tech - invest early in startups or IPO. Tesla was <10$ 2010-13 so it doesn't matter whether it is 100$ or 1k$ now you are ever on top. BTC was 10$ 2010-12.. now fluctuates 20-60k. Dogecoin is still 0$ you can buy it right now - with disposable cash. Not kid's tuition or pension.
It is not gambling when you invest next to nothing. 1k or 5k usd. Then potentially get 1m$ in a few years.
But if you can only spot Tesla or Apple or Uber - TODAY - obviously it is too late and stupid to buy them.
