Good for you but know that this isn't the bull season in full, but i will regard it as a signal for it coming soon,but being your first experience it's good that you termed it your first bull run, this is part of the profitability that comes in with bitcoin if you buy the dip it will surely gives you a better profit to take in along with time, there are times as well it can run dip but that doesn't change the fact that it's profitable since it's a volatile digital currency, there will always be a surge to run the price high whenever it's low.
