[Opinions] IF you could improve/add/remove 1 thing to bitcoin what would it be?

[Btcvilla]

Bitcoin atms being easier to use, I don't want to slip in an id to purchase bitcoin.

I would probably change the fees so that even smaller amounts can be sent without large fees. If bitcoin gets more expensive, you could have to pay several dollars to send one dollar of bitcoin.

I would shorten the confirmation time. Ten minutes is a convenient number but there is no need for it to be so long. There are benefits to a shorter time. I would take a look at propagation times and the orphan block statistics of alt coins, and come up with a better shorter time.

Wish 0 confirmations are enought at more places, most places require confirmations, but they offer no service that cannot be canceled later (like before the goods are really send). It would be only bit more work to cancel the order if not paid later for them and zero risk...

I understand confirmation is really necessary for instant services only

A transaction doesn't have to appear in a block to be confirmed. (Although appearing in a block is a higher level of confirmation.) If the transaction is accepted by a suitable number of nodes in the network, which can happen in seconds, then it is likely it is valid. An exception to this is an online transaction, for which it is easier to mount a double-spend attack, but online transactions don't require instant confirmation, because the product is typically sent hours later.

Summary: The 10-minute block time is not too long, because at a brick-and-mortar location, the transaction does not need to be confirmed in a block.

I would change two things:

1 Lower fees to allow micro payments
2 Faster transaction times

[ducatitalia]

AND why?
Just 1 thing, for I it would be transaction times, cause waiting for those confirmations is wayy too long sometimes  

To be clear...are you referring to improving one thing about Bitcoin the technology or the ecosystem in general?

From a tech perspective: Bitcoin core, blockchain and user interface comprehensive security measures
From a broader ecosystem perspective: Bitcoin Branding, Marketing, PR and Media Relations

[bg002h]

Shitty gambling adverts from people's signatures. You do nothing to promote a positive all inclusive image of Bitcoin by pandering and trying to profit from others vices/addictions.

Just because someone is a part of a signature campaign doesn't mean that they are only posting to promote said signature!

Personally, I am more turned off by people who put their Bitcoin and Litecoin addresses in their signature hoping for a handout  

It was fairly novel back in the day to be able to tip people who posted stuff that was helpful. There hadn't been a way to do that before. We take it for granted now, but, being set up to receive tips was kind of a way of identifying ones self as someone who was trying to be helpful...

The most critical in my opinion: Address the 1 MB blocksize limit to allow Bitcoin to scale.

I would fight to keep it at 1MB for the years to come. We need off-chain solutions for that and there are many in the works. Raising the block size would only slow down progress and harm those projects.

AND why?
Just 1 thing, for I it would be transaction times, cause waiting for those confirmations is wayy too long sometimes 

1minute is just as bad as 10minutes when in a supermarket, especially as this 1minute block time sometimes will also take 20minutes. We need other solutions to that and there are off-chain solutions.

But to answer the OP question:
What? I would add proof of stake.
Why? It's cheaper and better aligned with keeping the fees low and the network secure. With proof of stake there is no reason at all to have fees beyond keeping the blocks free of spam. Those holding bitcoins would have a huge incentive to keep the blockchain rolling even without block rewards and transaction fees. The claim that with proof of stake the rich become richer is based on the assumption that mining is a for profit venture but with mining (securing the transactions) being built back into every full client cause we can, we wouldn't have to worry about the 50%-pools and wouldn't be blamed for wasting energy on mining. Also those mining chip companies could focus on more meaningful stuff.
We could continue to give the block reward to proof of stake blocks and reserve the mining fees to proof of stake, aligned with the block reward halfing. At the next block reward halfing we don't half the block reward but we half the POW blocks, doubling the POW difficulty and adding POS.

Your suggestion is to make radical change to the protocol of BTC. There are plenty of altcoins out there you can choose from as you suggested, pow and pos combined.

User friendly Multi-Sig transaction support in the clients.

Would help improve security in an inherently trustless system, with everything from escrow to locking down wallets.

Its gonna be this way until regulations relax

As in to spread the word about bitcoin further?

[Yeezus]

I would change two things:

1 Lower fees to allow micro payments
2 Faster transaction times

Fees can always be changed, but woiuld still have to be profitable for the miners. I could see this being a problem in the future. I think third party programs can allow for micropayments just fine.

[niothor]

I would probably change the fees so that even smaller amounts can be sent without large fees. If bitcoin gets more expensive, you could have to pay several dollars to send one dollar of bitcoin.

The fees are there to protect the notwork from spam rather than actually being a reward for miners.

The total fees fro one day are in the average of 10-20 btc so miners are more inclined to find blocks with fewer transactions rather than missing them.
And in this mix a few guys spending 100$ daily just to bloat the blockain and you're going to see why we don't have 1 cent fees right now.

Quicker confirmation times, anonymous storage via blockchain (large files)

Good luck downloading the blockchain after two blocks if i'm gonna store there just a few of my hd movies.

[Mightycoin]

I would try to lower confirmation times, they sometimes take hours

Although we can pay extra fee for faster confirmation, so yeah.

[rebuilder]

Sorry, I don't get people asking for faster confirmations. I understand it's sometimes frustrating to wait, but faster confirmation times = less secure confirmations. If you changed the block target to 5 mins, then services waiting for, say, 3 confirmations would simply require 6. No difference.

Fair point, in hindsight 10 minutes is nothing in the financial world of transaction times!

[MoonTime]

If the mining could be easier then profits would be more. However this might cause inflation..

There is a significant difference between 1 confirmation and 0 confirmations, regardless of the time. Reducing the confirmation time from 10 minutes is beneficial in any transaction delayed due to waiting for at least one confirmation.
