thanks Graham
didn't even know about the historical feature!

1. Pure POW, Pure POS, ICO
POW is the most robust ... the network can even grind to a halt and the will kick back in once someone throws hash at it, so even dusty old mine operations are still working a-okay even though the market moved to the next new shiny coin ... age of operation will start to become a valuable stat.
POS also can cling on with a few dedicated stakers, but there is the kicker of coin distro that can cause issues
IOC are and will be always be high scam potential vehicles. Get the right team assembled and they can work, and after observing crypto for years I can only imagine the type of scams Silicon Valley VCs run into. Crypto is chump change.
Now a type4 category is on the horizon.
We now have stabilized market cap for +200 coins.
But launching a network is very difficult at this point.
So the platforms ... NXT, BTS, XEM will host 1000s of ICO assets ... but to avoid to prior scam stuff Dev teams will need to demonstrate reserve capital and it can likely be put in a multi-sig escrow (smart contract). There is also the burn method ... XCP, Master, and now BARR have shown that it can work.

A few Alts peaked at 150M$. Would be interesting to see some historical data (total Altcoins launched since 2011, #peak marketpap > 5M$, etc.). Not sure coinmarketcap.com or other sites make data that available.
150M$ seems to be a barrier, right now only ETH and LTC can hold that range. Ripple is another kind of beast so ignore their marketcap. But all 3 are standing on 150M$ ... so BTC xrp ltc eth are your 4 horsemen.
Next level down is 25M$ barrier (Doge, Dash are aiming to test it) ... they would be best served by focusing on being the liquidity used by the common man.
then 10M$ barrier (NXT, YB, XEM, BTS, FCT ... the platforms seem to each be acquiring a cap of 10M$ish)
then 3M$ barrier (the okay it's worthy of staying above 1M$ on down swings and basically 'made it' level)
then 1M$ barrier (note how many coins went over the 1M$ line on this recent btc price rise)
