Hello.
I asked a question yesterday which remained in a good answer.
By the way, I would like to know exactly if it is possible to transfer about 5000 BTC or 10000 BTC in a single transaction ?
Thank you.
As long as you have
BTC you can send as much as you have

But I wouldn't risk it to send that much (if I had them :p) because first it will take very long time to confirm the translation, and second you have to be 100% sure that you send them in the right place ( wallet/ payment).
