I was thinking about selling my jah and buying Back jah and ber when the prices have come down. Now im scared tho. I have never found a jah Rune and dont want to lose it. Any advice on how to make it Safe?

Always use a mediator for guaranteed safe trading.

That's kinda sad

Yes, too many scams happened lately, mostly from only One person tho

But if you are uncertain/worried - ALWAYS use mediator for your trades, no matter how small they may seem.
This kind of trade is Safe, and will be handled by d2jsp's own Mediators.
All you have to do is click the "Request mediator" when you found a buyer.
Both parts must post in the topic, and confirm the trade.

A few minutes longer trades, but it is the safe way.
And last couple years they gotten pretty fast on their feet to initiate the mediated trades asap.
