OP, are you a big liar or a dreamer?
I am only 27 years old .and I am using cryptocurrency & I am using this forum from 2013 . When I was 16 years old . But I was folish then I see Bitcoin price $60-70 but I didn't hold Bitcoin then. If I was bought and keep holding 10-12 btc . Now I could make a huge profit and get rich
Yes i been more then 45 years people using btc and investing on btc a much more. Because in this time they are in charge of a family so they are more inclined to seek income .so they take different approaches . And they lean towards Bitcoin

Coinerer is obviously not very proficient with the English language. The second quote you posted is not about him I think. If you check the first quote, he says "
I am 27 years old", but in the second post he uses an incorrect construction and says "
i been more then 45 years people...". I think he was trying to say that he knows about people older than 45 who invest and use Bitcoin, not that he is 45.
In order to buy bitcoin, we must have money on a card or a bank account. Here everyone will have problems, because you need to indicate the sources of origin of this money.
I am sure that casinos can provide receipts for such wins that can be shown to the banks and the taxing authority.
