You mean up this coin
https://bitcointalk.org/index.php?topic=3111392.0? BTCF- Bitcoinfinal. Correct me if im wrong.
If not then stop shilling out that coin either your are part of the team or just a hodler that simply recommend this shit token.
Have you consider on how many coins trying to get or say that they are the new Bitcoin?
No I mean Bitcoin fast! (Btcf)
https://bitcfast.com/First time to hear out this Bitfast and it seems no one is interested to this one.Before you they do try to dethrone BTC on the spot they should try first to dethrone BCH first on the list.
This is another futile attempt to ride with Bitcoin's popularity! And an alter ego unworthy of its name! I think there were so many variants of Bitcoin that supposedly have significant advantage over its predecessor but eventually failed! Moreover, the community have negative perception on projects that borrowed its first name from Bitcoin and we cannot blame them since most of this projects turned out to be shitcoins themselves.
I must say that the crypto community seems to ignore these kinds of offshoots since most of these projects hadn't even offered any major technical advantage over Bitcoin that they would certainly collapsed in due course. Reminds me also of failed Ethereum variants.

Well, this has 350% since roi and is upgraded version of Bitcoin. The old Bitcoin will become useless when is more demanded, it takes like 1 hour up to one day to trade with btc with also very high fee. This one here trades instant with no fee. Well something should be the future at least
Lol. A 350% increase wouldn't even attract investors much less end users! If you say you have an upgraded version of Bitcoin, can you specify its main technology advantage over it since you are assuming Bitcoin will become "useless"? Also, assuming your BTC clone have a fast transaction speed, maybe just for now, because maybe it has less transactions over the network - the reason for supposedly faster speeds!
I'm sure if you subject your BTC clone to Bitcoin's current network load, you will see it crawling since I understand you didn't even subject your BTC clone network to stress testing and the scary part is that it is not even secure as Bitcoin's network - can always be subjected anytime to a 51% attack! I was even wondering how much hash rate does your network currently possess now?
