My father is anxious pertaining to the fall and rise in bitcoin price. He has four(4) btc and he is afraid to hodl. He wants to sell at a lower rate. Any advice for him?
So your father needs to hold his bitcoin and don't need to sell at lower rate. But maybe your father can try to trade with 0.5 btc pair altcoin or usdt so he can have an opportunity to increase his bitcoin. I think that is an option for your father while he is waiting for the bitcoin price to rise again to the high price. I think it's better to do trading rather than just to hold his bitcoin and don't make anything.
The thing is, if your father is anxious about his 4 btc's he's probably going to be more anxious if he tries to trade some of that in the alt market where the volatility could be worse. If he doesn't need to sell for any important reason, i'd say try to get his attention to other things. Selling at a loss is definitely not the best option.
