So now, we are in the bear market, it will be another long days of holding and accumulation phase. But if you are interested to get back in Bitcoin again, it isn't too late since now that you have a business I guess you are successful with it. Why don't you reinvest again and try to hold them for a long time?
You have an experience of this market already, I'm sure it won't be that hard to make profit in the future.
I recommend bitcoin more often than altcoins which also lose value in this bear market as a long term investment. Bitcoin is still the best and they must realize that now is the time to buy a lot.
