We tell you that all the time. You choose to ignore it and press on. So we choose to ignore you and press on.
I don't recall seeing an answer to my point about altcoins vs scarcity.
Altcoins do not retain value, because miners mine them and sell them for bitcoin. The only way to mine bitcoin, practically, without a large investment, is to use a GPU to mine a scrypt hash coin. This means the altcoin supply is infinite, vast, and bidless, while the bitcoin supply is restricted, hoarded, and bid.
No altcoin can be achieve useful market penetration until bitcoin has first blazed the trail. Infrastructure must be built. By that time, it is essentially impossible to overcome the moat which is generated by bitcoin infrastructure, unless there is a huge utility value advantage due to technological change.
Almost all altcoins are pump-n-dump scams.
Some altcoins are technology testbeds, like bitcoin. One may some day prove useful enough to start to retain value. It hasn't happened yet. There is nothing on the horizon. Bitcoin has a 5 year head start.
Litecoin is for contrarians and day traders, which are enough to keep it moderately liquid, so it is the exception which proves the rule.
