Voted for You Had A Great Deal.

I think that you had a great deal, because even if 1 MAGIC token will worth only $0.001 USD, then 20 000 MAGIC tokens will worth $20 USD.
1 Steem is currently (2019.01.18, 08:05 CET) worth $0.334492 USD, so 3.814 Steem is currently worth $1.275 USD.
Based on the prices above, this is 1568.627% profit.
Even if the value of the Steem goes up to $5 USD, it will still be a small ($0.93 USD) win, because 3.814 Steem would worth $19.07 USD in that case.

But this is only my opinion. This is not an investment nor betting advice.
There is no guarantee for the value of the MAGIC tokens nor for the value of the Steem. Both of them can go up and down.
