IFC is just like Doge, it may need some technical upgrades but other than that it works just fine. I have been holding some IFC since 2012 and will continue to do so.
One problem that I see is we need more miners. The more different miners, the smaller the chances of 51% attacks. But this goes for every crypto. This is not something that IFC suffers from alone. If support for BitcoinCash would drop severely then it would also be easy to attack that is someone wanted to do harm. In the end 51% attacks cost a lot of power (money) to do and the return isn't that great.
One more thing is that IFC doesn't have a real team so there are multiple wallets out there that people don't trust. I still use 1.8.8
To succeed more you need people actively talking about IFC on Twitter etc. That's where all the crypto people are today. I don't know anyone else (in person) that uses BitcoinTalk even though I still like it.
Which version of the wallet is the user's free choice, since everyone knows the importance of developing miners, then we should support the 1.9.1.8 version of the wallet, because the 1.88 version of the wallet fee is no longer suitable for IFC, without block awards, while the 1.9.1.8 version of the wallet charges 2/1000 of the handling fee to the majority of miners, 1.9.1.8 version is more conducive to the development of miners. Although my2008 has encountered some resistance in implementing the one-person-one-mute mining machine program in the Chinese community, it has achieved certain results, the number of miners is increasing, and the consensus is also expanding!
