First of all, this post is dedicated to 
Fear not where now we have an alternative way in buying in. #esteemapp offer users to buy in via credit card as soon as one has bind their credit card with Google Play, and user can purchase #estm points via credit card and will be able to use these points in exchange with upvotes, and ultimately convert to #steem. Let's get to some calculations.
As at current market price, the highest exchange value should be 50k estm for RM404.99.
According to Bloomberg, current price for USDMYR is 4.185. 404.99/4.185 = $96.77 will be our initial investment.
Once we have the #estm in hand, we will be able to use the "boost" function in exchange with #esteem upvotes when we create a post.
According to current vote value, 2000estm would worth $4.154. For 50k, we can do 25 times. Let's assume the costing stays unchanged, it will be 25 x 4.154 = $103.85. Cost of investment $96.77, take back $103.85. I don't dare to say it's a profit, it could be extra charges on the credit card payment, or the bank does not follow Bloomberg pricing.
There you have it. From what I see, it's definitely worth it. Provided each vote has to be above $4(for 20 steem worth), otherwise the new #hf21 curation curve will eat up a huge portion of the author reward, which I'm currently suffering. See a $2.00 upvote came in, but the post reward shows only $1.60.
