This is a very interesting point you make. The concept behind Merit is super-cool, but the practic implementation quite sucks. As a latecomer I'm personally totally stuck as far a "proof of growth" is concerned (for the reasons I've explained in a previous post of mine) - and this applies to every newcomer so in other words the network CANNOT really grow this way. The "proof of growth" should be renamed "proof of whale" since only people with their bags full of Merits will eventually get more. I've also given a try to mine Merits with the wallet but as a result I've ended only in wasting electricity and getting ZERO merits. On top of that the news that coins will be sold by the team to people makes it really look like just another Ponzi. The only realistic way to get the coins is to fucking buy them? WTF? So you guess what? Good project on paper - but in the real world it has probably no future.
I read other posts in topic I missed. First of all, it's not begging when you ask your inviter for more invites. Invites are here and yes it depends on a) mining b) CGS. So I am getting more invites with wallet that invited many people and has some balance and do some mining than for example you. It's hard to tell who should get invites in decentralized way, and this seems to me pretty good solution. And we, people, community, are here to compensate it. There's nothing wrong asking someone higher in your ambassador tree for invites, I did it before too and that's the point of community. Even someone outside your tree will likely send you couple of as KAMO mentioned. I sent you 5 more invites and if wallet invited by you will need invites just let me know and I will send them too. It's not about begging it's just about letting me know, so invites will be spread the best way they can be.
Also there are more ways to get invites but if your inviter has some (in your case me) or someone upper in a tree, there's no reason avoiding to ask. As was mostly mentioned:
1. you can get it from centralized pools, starting with Parachute is great, but you need to wait until end of the month, it's similar, you have to ask for them via form (not begging!)
2. try to get 20 MRT to your wallet and you'll be qualified for Proof of Growth rewards, it's not true only whales get it, you'll get couple rewards in a month even with 20 MRT wallet you have also a chance to get invite from blockchain this way, check your rank here
