Embercoin is an investment that offers a high rate of return in a short period of time, in other words it is a risky investment. I am personally willing to take the risk. I think the key is to know when to buy and when to sell.
I bought a couple of million at 5 satoshi about a week ago. The price reached 16 satoshi 3 days after I bought. Now it is back to 7 satoshi.
I will hold until October for sure. That being said, I anticipate a huge dump in the second half of October as the staking reward gets reduced considerably by the 1st of November.
