Let me ask you a question: if your neighbor hadn't decided to invest in Bitcoin back then, what would be his financial status now? He would still have to pay his bills and stuff, wouldn't he?
What you described in the OP is not an irony but an example of a bad financial and investment decisions. Obviously, his problem is not in the bad timing when it comes to Bitcoin investments, but in the fact that he doesn't have the constant source of income he needs to cover his basic expenses. It is just stupidity that he waits until the last moment to sell the Bitcoin and pay his bills. But that's just an excuse for bad decision-making on his part, not an irony.
Okay. But please can you define what is an IRONY with examples? So that I will understand it more.
