I have noticed that there have been more GTM masternodes come online due to people dumping. You can look at the people dumping as a positive as it gives many people that were looking to buy a GTM masternode a few months ago but couldn't because the price was out of their reach but now they can which is what I think we are seeing here.
I thought like they actually waited for too long, might be months to see and take chances to grab huge amount of unbelievable cheap Gentarium. Such huge dumps days ago (nearly one week ago) of Gentarium does not occur too often. I waited for chances but I doubted myself and only set up my buy orders around 7k satoshis with very limited amount. Because I did not really believe that I can have opportunity to grap Gentarium at such low price. In fact, GTM dumped much deeper than 7k satoshis before recovering and stood nearly 10k satoshi recent days.
The price should increase a lot more over the long term as GTM continues to grow. Lets not forget that the dev team have much more to come and that this is just the start. There is still the Asics platform that needs more improvements and then there is the Node Monitor that is yet to come and also an investment fund. So we have a lot more to look forward to with GTM in 2019.
