I dont mind people being sceptical about bitcoin but what I dont understand is their unwillingness to even do their research about bitcoin first before reaching an informed opinion about bitcoin. You have free access to the internet to make your own research. Bitcoin has been around for more than a decade, we should not have to tell people that bitcoin is not a get-rich-quick scheme neither is it a scam.
They are too lazy to do that, that is one of the qualities of no-coiners. They want everything to be spoonfed to them, they want others to convince them first about why they should buy Bitcoin or make an investment in it, and after someone convinces them, they also want the privilege to then blame them for their suggestion if the price of Bitcoin goes down after they buy it. Such people would never do their own research to find out if it is good for them to make an investment or not, you will only find them regretting later on, but they still won't change.
A no-coiner will keep doubting without taking any action when the market is low, they will keep watching it go up and don't do anything other than asking questions that they've asked so many times already, and then when the market reaches a good point, a point that they have never expected it to touch, they regret everything they've just been through, but, they don't learn from that, because when the market drops again, they will repeat the same course of action instead of changing their mindset.
