Thanks @sandwich for your sound and useful tips. Just before reading your post I did what the EOS website suggest (I'm referring to Step 2 and bullet point #8 of this post). So as the EOS website says, I claimed my tokens with 4500000 gas limit in MEW. This is insane! I ended up paying $22 just to claim 211 tokens. EOS or MEW should warn users about the amount spent when using gas. Now it's too late. I had a good lesson today.
