I just did some faucet mining and got 0.00016519 BTC -- So, in their terms 16,519 Satochi.
It was sent to my wallet and it's all good, however, when I tried to send it to my "savings"(LOL) or  a holding wallet,
the Armory wallet tried to charge me 0.0001 BTC as a "transaction fee" and would refuse if I have changed the amount to 0.0000.

I was under impression that transaction fees are voluntary and not mandatory and this is trying to take in 1 swipe majority of my savings, the whole 10,000 satochi - this amount takes many days of work to collect.

Could anyone more knowledgeable explain how it works?

Is there a way to send those coins from one wallet to another without any fees?
Who is collecting them? (I use local wallet, so my computer does the processing).

What are the fees (if any) for other coins and wallets?

Any other info in this regard would be greatly appreciated and very useful to all newbies.


Thank you.
