Coin Control Feature from ghobson's blog

Hi Everyone.

Today I would like to talk to you about the coin control feature.
This feature is turned off by default and can be enabled in settings->options->wallet tab.
Once enabled you will notice a new section in the Send and Deposit section.
This feature allows you to control where the coins come from in your wallet, specifically which inputs to use when sending or depositing coins. By default the wallet will choose for you automatically.

Recently a user asked me on discord why he could not send or deposit a large amount of coins.
Each time coins have to come from an input in your wallet it requires a certain amount of bytes
to store it in a transaction, before it gets added to a new block.
For example it would cost more transaction bytes to send 1000 ROI coins from 10 different inputs than from a single one.

Each time you receive coins from pool or other people, it will be stored as its own unique input in your wallet. If you want to increase the amount of coins you want to send in one go (or deposit) you will need to use coin control to select as many inputs as can fit in a single transaction and then just send it to yourself ( one of your receive addresses ). This is also known as consolidating your input addresses. This way the next time you send or deposit coins it will come from a single input, which is much cheaper to send ( less bytes means lower fee's ).

In the future I will make a tutorial video showing you how to do this.
I hope this was helpful.
