One question.:They sent me all my claimed IOTAS in four transactions to the same destination address. Come-from-beyond sais on the slack (as an automated wellcome message, when you log in) that nobody should use the same address as a recevier for more than one transaction. I guess for security reasons.
Can and should now resend my claimed IOTAS to another new address, or is yet too late for me?. Can everybody steal this Iotas if I don't move them right now?.
You are safe.
You can receive multiple time on same address but for security reasons you should spend only once from that address.
The wallet does it automatically, when you send some iota somewhere, it generates a new address from your seed and send your iota left to it. This way you never spend from the same address.
What you should always try to avoid is spend from address, then receive again on that address.
Thanks for your explanation!!!!!!.
