Sumokoin's DEV clearly stated that they respect Monero and they even collect donations. So imho there is no competition between xmr and sumo.
1) There have been no proof of donation to Monero.
2) Donating to Monero doesn't magically make Sumokoin legitimate. It's a scam.
Stoffu please stick with Monero that apparently you support and love and I dont blame you for that and stop considering Sumokoin as a threat.
It is not. However it makes me happy to know that such a "knowledgable" Monero person ( you are all over Monero's git trying to solve Monero users issues ) considers a 7 months old coin a threat ( although I repeat it is not a threat to Monero ).
