If you are still planning to get into Bitcoin, don't post anything about it in family group chat or on your WhatsApp status, this was my biggest mistake.
That's apt! This should be a good advice to the introverts among us and those who like to keep a low profile. Regrettably, the extroverts and those who run Bitcoin businesses won't feel comfortable keeping mute about it and not constantly updating their status with claims to such. I do believe that everyone should guard whatever they do to earn money if divulging or exposing it won't make them more money. I, for one, I don't put up anything crypto related on my WhatsApp status. The only place I can do that is on my Telegram dp or on Twitter. I did a bit of irrational display on Facebook when I started because I was carried away in excitement. Now I know it defiles my privacy and I've stopped.
Talking about your uncle. Your response wasn't harsh. However, sometimes it's good to just ignore people like him with silence. As they say, nothing wins like success. Cancel all his insults with your success story. Hopefully you will achieve all that this coming bull run.
