Is there a single exchange where MEC can be traded for USD?
The comparison for cryptocurrencies is BTC, that is the 'base' currency.
And now, last week and for the last month, you would have been better off in BTC than USD.
MEC has been very profitable for trading, but not for holding.
The same logic would say that it is worth spending 100 BTC for an ASIC that will only ever generate 50 BTC, because you think BTC will increase against USD.
Either way (MEC or ASIC) you end up with less BTC than you started with.
No...although Cryptsy is working on implementing USD into their exchange and I am working on an MEC-focused exchange that will also buy/sell MEC for USD (albeit initially, the exchange portion of the service will not include USD for legal reasons -- I will buy/sell as a separate service.)
Of course you would be better off in BTC than USD over the last month -- BTC is almost worth 3 times what it was at its October low. I assure you that the Bitcoin price increase is not breaking news on the primary Bitcoin Forum. You would also be better off in LTC or MEC than USD over the past month.
Since October 8th, the Megacoin market cap has risen from $221,000 to it's current value of $364,057 -- a 60% increase. Just because you can't perform the calculations on your own (current Bitcoin price multiplied by the MEC:BTC ratio) doesn't make it any less of a fact.
By your logic, almost everything of value has been tanking for the last month. Sure DOW hit an all-time high today and is up 5.5% over the last 30 days...but in terms of BTC the BTC ratio it's down over 250% in that same span. The value of my house is down 250%...my salary has decreased over 250%. You see how your logic is flawed? It wouldn't make any sense for everything to rise simultaneously with the Bitcoin value -- if anything, you'd assume the opposite would be true because people are going to be selling altcoins to move into Bitcoins during rallies like this.
Unless you live your life and determine the value of everything based solely on Bitcoin...which I've never met anybody who has...you are flat wrong. Just because one thing outgains another in value doesn't mean they can't both increase in value. You must have gotten killed on your Iowa Basic tests when you were a kid
To me, I determine the gain or loss of value based on purchasing power. In my case, it's a combination of USD and any applicable inflation. If my investment is outpacing inflation, it's a good investment. Sure BTC has been amazing...but there are times when BTC has dropped and MEC stabilized my portfolio.
Another thing you need to realize is that once the Bitcoin price stabilizes...interest will start flowing back into altcoins. This might affect the Bitcoin value slightly...but due to it's $4 billion market cap it doesn't take a lot to send altcoin prices up on a rocket. This situation represents a rare opportunity to really get involved in altcoins before they blow up again...and you're looking at a 1 dimensional image instead of taking advantage.
If you want to go around and tell everyone that everything they own is going down the toilet in value because the Bitcoin value is surging, that's your right regardless of how illogical it may be. I think everybody would agree that it isn't constructive...and if that's honestly what you believe perhaps you need to learn the absolute basics of finance before drawing future conclusions...but I'd really like to think nobody truly thinks like that -- please tell me you understand the basic concept of value.
