I sold my tiny bit of Burst back when John McAfee recommended it. Decided to buy back today. Nice to get it cheaper, I wish I had done that with all my crypto. Burst was fun to mine but I don't want to do that again. I do think it will appeal to newbs that want to try mining, like it did to me in late 2017.
Mining sites are still wide open, but high diff levels will make you think 2x or not. But as long as the burst can continue to be active there is no harm in trying and holding it back until it penetrates the moon.
