On which basis these expectations were built?

TX seems severely undervalued.Considering the low supply, it could easily reach a few dollars (could happen suddenly, at any moment), it is not uncommon for things like this to happen, and given the masternode feature, chances are higher  

You will need to create a new address and send the 10k to it.

It does but its not a good version https://github.com/transferdev/Transfercoin/releases/tag/1.2.4   when i say not good it has freezing issues when there is over 130 Masternodes in the list..currently there is not so it may work ok....   i have a better version on txproject.io that i uploaded to my amazon....

The price is still low, good time to buy. Like it was said, it could reach 10$ easy.

I uploaded a version that has the freezing issue fixed a while ago here https://txproject.io/


But some good news we will have an actual official release coming soon.

the million $-question. With the next masternodes hype?

Freezing is not a big issue. Why someone can't download v1.2.4? It's simple. Maybe you mean someone can't download v1.2.3 because it's removed from Github?

 InfernoMan has not left but his is his side project now since got hired onto CRW and TX is in the hands of the community with the help of InfernoMan  as needed.
