Hi, thanks for your interest and sorry for my late response.
Regarding 'sweeping' or sending, it's something I've done many many times - for myself when they were low value but also more recently for friends.

I would agree with iBHK8 to use something like Ballet for the forked coins, 'airdropped' stuff etc.

However, I would first - cautiously and with very well considered steps beforehand - send your BTC to a hardware wallet address then only aftwerwards to go play with the BCH & small-fry other stuff.

I don't know if it's possible to 'sweep' without exposing the private keys online so the way I have talked people through doing it is with an out-of-the box £200 air-gapped (wifi off from first start-up) laptop with electrum installed on it from USB stick. Then with electrum also on your connected computer, you can set up watch-only wallet on that one, inputting the public key which will enable you, with the wallet able to read the blockchain, to prepare the transaction (the amount (max), the send-to address and the fee). Then you need to export the unsigned transaction and take it (either on USB or by QR code) to the air-gapped machine to import, sign and export again. You can then, with the signed transaction, input it back into the electrum on the connected machine and broadcast.

There are many variations on this theme with various degrees of security. It is essentially the same as safely spending from a paper wallet and you'll find many processes for that - some with illustrations etc. The critical thing is to remember is that until the signed transaction is broadcast and has been confirmed, you don't want there to have been *any way* the private key could be accessed by anyone (or some malware that will help itself to your funds). (Scanning the QR code to an app on your connected phone to sweep your BTC, for instance, can become a race between your legitimate app sending you the funds and malware on your phone sending them to someone else)!
