and I believe you should try to buy into those projects that will give you a lot of coins for the amount rather than buying just a few maximum.

I think that's a misconception. The amount of coins you can buy does not say anything by itself. First, you have to put it into perspective by looking at the maximum available supply and the distribution mechanisms. In the end, the information to be determined here is how many % of the maximum available coins you can buy. So you can buy 2 Coins of a project with a maximum of 200 Coins and have 1% of all Coins. If you buy 1000 Coins of a project with a maximum of 100000 Coins, you have 998 Coins more, but only 0.1% of all Coins. So your share reflects once 1% of the market capitalization and once 0.1%. Then you can enter a consideration and try to assign a number to the potential marketcap and compare it with the current marketcap. As an example, one could compare the Travala.com project with Expedia.de and derive what price in this case AVA will achieve when Expedia.de reaches a market cap of X%. This is a casual description, but I hope the idea gets through. Of course, this is not a basis for a comprehensive DD - but it should show how meaningless the number of coins is without providing any context here.

Bought Polkastarter in November as a Moonshot. Feels like I should drop it. Nearly 300kk MC..

e/ Thanks to Polkastarter I learned what the term IDO means. It's similar to an ICO, but provided through an decentralized exchange. IDO = Initial DEX Offering / basically Initial Coin Offering through a decentralized Exchange.
