This might be the largest update in crypto history. The devs said he will release the source code soon and this can be confirmed by others.
The most impressive part for me is not the crazy good ux in the offering or the Link feature which feels unreal when you use it but the time it took to do 1.6.0
I am also a investor in digibyte and with a fairly large development team have been working on the 0.12 and now 0.13 codebase for over 6 months.
1.6.0 with codebase 0.13 took 5 months to complete. This is what would have me worried if I was other coin devs.
This is why I invest in Dash and lately Gulden. I have started liquidating my positions in litecoin.
