It is possible that DDC is in for Bitcoin in the long run. As they release the statement, it is possible that they have the resources to accumulate 5000 BTC in three years time. Remember Bitcoin won't stay at this current price and in the next two years, BTC will possibly be on the bear market where DDC can acquire Bitcoin at a possibility of 30% to 40% less than the current price.
They can be less serious else they wouldn't have started with such amount in their accumulation journey. So it's certain they are in for the long term, and must have done their evaluation before arriving at their decision for 5000 BTC accumulation within the frame of 3 years.
I think in the long run, probably, by the next bitcoin circle people will start having a different view about their decision. Right now the timing seems worrisome.
In my belief, I think DDC plan of accumulating BTC in the next three years is brilliant. They can acquire BTC at a discounted price since as I stated, the next 3 years will be a bear market for BTC if the cycle did not change. Then after a year of that 3 years accumulation comes the bull market for Bitcoin where they can possibly see a significant increase in their Bitcoin holdings value.
Opinions on this move differs as some persons are concerned with the time of their buying even as it seems brilliant to get into th adoption just like other institutions have done. What they spent now could have purchased more bitcoins for them if they could have at least waited till the bear market. A lot of people would have taken it differently from what the response are now.
