I'm not aware of any other 'regular' cryptocurrency writing contest hosts/sponsors, but do see some occasionally run by individuals.
"What can help them get better?"
That's a tough one, because they are doing a pretty good job within their means...The increased spamming in comments just for votes can only be reduced by 'not' giving votes to them.
As far as the awarding goes for merely submitting, regardless of quality might be addressed by limiting those low end rewards to a handful, like @originalworks used to do.
If they are attempting to 'help' people in the developing countries by paying forward, I think they can come up with a better way. I'm all for helping others here on this platform.
Most of the 'top' writers are well deserving of their wins, regardless how I place, I salute them. We never know 'who' it is that actually reads and selects entries, nor their criteria, comprehension level or expertise. Therefore, it is often a hit-or-miss for the top performers.
