Future improvements

[traderethereum]

         I do not think Bitcoin needs significant improvements in the future because it's good as it is. Your comparison is not very good with upgrading to your phone. Upgrading to the phone comes from the need for greater security against hacking. Bitcoin uses a decentralized system, and hacking is almost impossible. The only "upgrades" that can be made are trading exchanges, both for their security and investor investment, as well as adjustments to transaction taxes.

No, bitcoin will need significant improvements in the future if it's necessary because if bitcoin is not doing that, then bitcoin cannot serve the best works for us.
Upgrading the phone is necessary if we want to get a new update from the developer so we could get better apps for our phone.
Yes, the exchanges must be upgraded the security from time by time because they need to protect the member, the asset, and the website itself. Without making an update for the exchanges, we will see there will be many hacker cases in the future that will happen.

Of course, what you have indicated may change the positive attitude towards Bitcoin, but fundamentally other factors are much more important to it. I am convinced that only the introduction of Bitcoin into the real economy can quickly change the existing reality. So far bitcoin is considered as a means of investment. As an asset, but not as a means of payment. Only when Bitcoin becomes a full-fledged substitute for currency and with the help of it you can buy chips or a bottle of soda in the store, then real success will come to Bitcoin. Of course, the decisions that you described are important from a technical point of view, but still this is secondary.

The lightning network [...]to use it only for conducting small transactions.

saying lightning network is created for conducting small transactions is like saying bitcoin is created to store arbitrary data in OP_Return outputs!
LN is mainly created and used to offer the ability to send/receive a large number of transactions at the highest speed possible while still being decentralized and be on top of bitcoin. using it for micro transactions is only one of the things that this design can offer.

Well honestly, the current status of the Bitcoin is alreadt been fine with me, on how I used it. And not only that, the current Bitcoin features already been satisfying the needs of its users. But more than that, I am not against the Bitcoin upgrading or future improvements because for me, continuous innovations and futher developments is really necessary to keep the Bitcoin running.

Bitcoin privacy can't be over emphasized, it gives absolute confidence. Upgrading whatever aspect that needs to enable it be a pioneer coin for global technological growth is surely a proper way to put bitcoin on top.
