Hi,

Could anyone please list me and and all disadvantages of Electrum in comparison with bitcoin-qt from any and all aspects such as:

- not being able to withdraw from particular websites if using electrum desktop application
- sometimes or always not being able to send or receive funds if coming (or going to) bitcoin-qt because of using Electrum
- high probability that Electrum in the future won't be able to be used (e.g. permanent server shut down)
- limited free usage (free trail)
- limited incoming and/or outgoing transactions per X time interval (day, month,...)
- limited amount of balance being able to be hold
- limited amount of incoming transaction
- limited amount of outgoing transaction
- not being able to send funds from Electrum to X location
- Electrum fees
- etc

So since I have giant trouble with bitcoin-qt im looking to switch to Electrum but would appreciate if anyone could please list me all Electrum's disadvantages.
