In a case scenario where friends are gather they normally talk about different things which lead to arguing and bragging (crypto currency & Bitcoin) who has more asset they do this to lure you out and spill the bean how much is in your possession. People who are wise understand the scheme going on but most people just want to get along the flow eventually spilling the bean.
Now if something happens to that person's Bitcoin/Altcoin who is solely is responsible?
That's right. Boasting happens to people who are not self-actualized enough in life, and by talking about their investments, probably even increasing the number, they try to seem successful and businesslike. But the mistake is that people can hear everything differently, and someone who is too talkative may be in danger, even, one might say, threatening the life of that person. There are very few people in our social circle whom we can trust the most; everyone else will only rejoice at failure, no matter how harshly it is said.
I often say that modesty is a good quality; you shouldn’t be something you’re not; on the contrary, you need to be simpler so that people don’t have to envy you.
