I know the ship has sailed because I have finally put money into Bitcoins and every investment that I finally get around to making is at the end of its hayday.

Do you realize how illogical that statement is ? If 100 men invests randomly, some will become millionaires, some will break even, some will go to the poorhouse, and a host of results in between, it's like tossing a coin, sometimes you get heads 3 times in a row, that doesn't mean you're blessed or if you get 3 tails in a row that doesn't mean you're cursed. It's just statistical variance.
