3  Bitcoin / Bitcoin Technical Support / Few questions (First time Lighting,Wasabi & CoinJoin,using Bitcoin Core offline) on: April 24, 2020, 01:03:35 PM
Lighting :

- I have never used lighting before and I want to use it to send someone some sats, i have funds in my bitcoin core wallet and i prefer desktop wallet as my mobile is android 4.3 and most probably wont support lighting wallets, i do not know from where to start and how to make a swap from on chain funds to lighting funds and so on, maybe explanation or youtube video or something will help a lot

Wasabi & CoinJoin :

- what are the pros. and cons. of wasabi and join market, which route shall i go for the best privacy.

- to avoid having my coins flagged/rejected due to being coinjoined if sent to a exchange, is it a good practice to send the coins after mixing to a new bitcoin core wallet/address and from there send it to the exchange, if no, how would you advise me to send the coinjoined coins without being flagged

Using Bitcoin Core offline :

- i have my bitcoin core wallet fully synced (bitcoin core 0.19.1), can i create an address while i am offline and after i have fully synced the wallet, if yes, then how there will be ever an coincidence that the offline generated wallet is already generated or will be future generated ? (I'm referring to the (How to Deposit Funds) in this article https://en.bitcoin.it/wiki/How_to_set_up_a_secure_offline_savings_wallet)

- lets assume i have a wallet with 1 btc, would bitcoin core after being fully synced and then go offline allow me to send 0.5 btc to address x and 0.5 btc to address y
and after the internet connection is back and i am online, the transaction would take place immediately as if it is just waiting to sense internet connection in order to log the transaction on the blockchain or not possible and i must send the funds while i am online

I have recently installed VMware 15.5 on my PC and created a fresh Windows 10 virtual machine to host a fully-synced Bitcoin Core 0.19.1

Everything was super smooth until yesterday where the Bitcoin Core was so laggy/choppy and it was a serious hell to process and/or download new blocks.

The specs of the Host

CPU: AMD FX-9590 8-core RAM: 32 GB OS : Windows 10 Pro x64

The specs of the Guest

CPU: AMD FX-9590 8-core RAM: 28 GB OS : Windows 10 Pro x64

SVM Mode is Enabled in the BIOS and I have the (Virtualize Intel VT-x/EPT or AMD-V/RVI) enabled in the VM settings
