I am not forgot. The chain is stable? On the start blocks were rare, then after ASICs come to the pool blocks were extremely fast. Do you ever think about stability? But in other ways the chain is stable.
About chain I wrote earlier. Wallet, only web wallet! Only one centralised pool! Exchange? Do you think its a good exchange?
Electrum wallet is good, will be wait. Why do you think that exchange allow pools? Is exchange associated with pools? Its interesting.
Market a bear, you are right in it.
Of course the block frequency increased as the net hashrate increased then slowed down again as the difficulty adjusted. Not sure what your point is there?
Again not sure of what your complaint is with regard to the wallet - there is a web wallet now and an electrum one coming very soon. Do you want a third option?
Every coin starts as being centralised - if the code is released too early then that makes bug fixing a nightmare with having to get multiple pools/exchanges/standalone wallets to update to the latest release. The devs are doing absolutely the right thing by not rushing to release the code. If you don't like that then maybe just come back in two or three months?
The exchange is Bisq which personally no I don't really like. It is a reliable exchange though and you always have the option of OTC through the Discord channel if you want to buy/sell - thousands of BTR have successfully been traded there. No idea what you mean by 'is exchange associated with pools?' AFAIK the BTR dev team have nothing to do with Bisq other than having their coin listed there.
Overall I really don't understand what you are complaining about - this is a new coin and is actively being developed. If you want/expect multiple exchanges and wallets to be in place on day 1 then you simply have unrealistic expectations.
