I have... I have a quite old deck... but I've played for a couple of years. Even been in the last league for a moment... but then, just had other priorities. For me, the effort to help other ventures is more valuable for Hive, because Splinterlands is an established venture. They know what they are doing, and my value towards them is much less when compared with other newer projects.
So, basically, I'm trying to push more good projects and with this I am not saying Splinterlands should not get my support, its just I am only 1, and so, helping who I think I can help, becomes that priority.
