Normally, investments take time before profit comes. It is not something that you just invest immediately and start expecting profit. This is the reason why a lot of people do fall for scam, because scammers will promise them that they would be making huge percentage in a week or even a day, and they would believe it and fall for it because of their greediness.
For the case of legit investments, slow and steady is always true and applicable; hence what OP is empathizing on this topic is fully acceptable for me.
Yeah, anyone who wants to be an investor must be ready to have patience and wait for a long term. if you are investing in something like bonds, you know for sure that you would be waiting for a year before your profit comes. The reason why a lot of people likes to hurry when they’re investing in cryptocurrency is because they have seen that cryptocurrency can increase within a short term, so now all of them wants to make that profit immediately and cash out.
