Any Disadvantages With Having Small Transactions In A Wallet?

[seafarer124]

Having quite a few small transactions in a wallet, would it be advantageous to send them all to another wallet and return to your main wallet as one transaction?

The reason I ask is I am not really familiar with how transaction fees work when you spend BTC. 

I use Electrum, what fee should be set?  Is the fee the same for every time you send BTC?

You can send to yourself, to a new address, in a single step.

Also you may want to group small transactions with the big "bulk" of the result and repeat with each transaction until completed. Something like every day or so, so the priority for your transactions ensures a fast confirmation.

But later if you want to spend several small pieces, you will need to break your bigger bulk transaction every time and pay more fees. It's a difficult thing to plan.
