Most of your questions are already answered many times by experts. I have a query which I wanna ask from you. How are you coping the price volatility of BTC? Like if you received 100$ worth of BTC 10 days back then they must be around 80 or 90$ by now. How you adjusting this price volatility or you are happy to keep BTC no matter how much they vary in price.
