If asked how I feel if they don't invest in bitcoin, it doesn't matter, the important thing is that we have given an overview and accompanied by the risks. If they choose something else, that's their choice, but what is clear is that investment is an activity or process of investing capital for the long term, with the aim of obtaining greater profits or results in the future.
I feel bad when someone makes mistakes despite being warned of it's detriments, I feel it matters especially when they invest hide money into pump and dump schemes and sometimes, you'll be sorry for even introducing the person into the crypto space. But when you give an investor orientation and he chooses the best which is Bitcoin and invests more of his funds into it, then probably chooses to diversify his smaller units of funds into other shitcoins and hold, then you're assured that his risk ratio is minimal since Bitcoin risks are much smaller compared to altcoins and shitcoins.
