I don't see any reason for anyone to not actually buy ethereum, even when right now the prices of the coins are down (ETH costs 90$), but it does not change the fact that ethereum is one of the best coins that you can put your money into for the long term. It does not mean that the coin is never going to do well, just buy now and wait for it, you will surely see it go back up
As you say, many of the people he meets do not buy but not all think like that. There were those who bought when ETH returned to the $ 200-300 range because they thought it was the bottom of ETH. However, ETH continues to decrease but does not make them feel they are wrong
