What feature and/or change would like to see in Bitcoin?

[xmax]

- increased capacity of txs/second
- reduced size of blockchain

I want to have my cake and eat it to! These are 2 conflicting requirements.

Am I correct in stating that the size of the blockchain is what makes it so secure?  If this is the case, why would someone want to reduce the size of it making the whole system more vulnerable to attach.

I want Bitcoin to be popular. I want it to be watched carefully by the government but not stolen by the government. (I don't want the government stealing from us) etc.

for me the most important change will be the faster confirmation times. that's something that can get the adoption even to another level. i only don't think we'll ever see this being implemented.

It would be nice if we could include in the Bitcoin protocol some sort of reward system for running a full node wallet.  I think that would increase the network's security by encouraging more users to run a full node and take some of the power away from the big mining corporations that have most of the control over the network.

I wish that the confirmations get faster because that's not useful to everyone to wait at least half of hour to making it's deal or trade, and as Bitcoin's looking to become a global currency it should facilitate the transactions for every user

To me bitcoin is growing and I would like to see lot of focus put to the privacy part. When it is done so, then people will always be sure of the safety of the coins they have. I will also like to see the bitcoin in general coming up with a body whose mandate will be regulatory and therefore be able to control the flow of the coins in the economy. A control to mining especially is very important.

- fast confirmations
- increased capacity of txs/second
- reduced size of blockchain
- ability to re-transmitting tx if the fee is insufficient (adding/increasing fee after tx was done).

If all that was done on the level of blockchain, without any sidechains etc I'd be pretty happy.

Agree with this. but for me the most important is fast confirmations and increased capacity of txs/second. because i'm gambler need fast confirmations

How fast would be enough for purposes such as gambling? There are reasons why confirmations are not instant. But I agree, 10 min is probably too long these days.
