Yes, he who boasts about his winning get taken down. You never see people boasting about how much money they have in the bank, those that do get taken down as well. So when it comes to crypto same principle, don't blab about it when you are making good money. Don't even mention much about your alt coins etc. Since with crypo it is really easy to take the coins with just a click, the criminal element would even come to your door to take it when they get a snif of it from your boasting about it in parties etc.
