The "quick" solution to store BTCs on your PC
In general, the safest way to store Bitcoins is by means of a desktop client. However, many of the virtual wallets that are currently available require us to download all the information about all the transactions carried out from the very beginning of Bitcoin's time, before we can even think about starting to use them. With Electrum you can make use of a compromise solution:
- Store the wallet on your PC.
- Carry out transactions by connecting to remote servers.
Electrum doesn't download the block chain.
By downloading Electrum to your PC you'll have a lightweight and secure Bitcoin client.
