I find it very difficult to keep seeing the bigger picture when there are so many new projects. For instance the airdrop and ico branch. Overwhelming! Is this also a problem for my fellow crypto enthousiastics?
No, it's doesn't. Do fiat or local currencies are affected by threats? In. The future every country has its own cryptocurrency aside of Altcoins that is being circulated globally and every cryptocurrency are not related to each other, they're just have roles in each field and most of them were used as trading and conversion into the next Altcoin or cryptocurrency. Even Bitcoin hard forks have nothing to do with each other.
Well, you can't say that all countries will have currencies. Maybe some won't take the risk of going fully digital and maybe others will accept some of the existing coins instead of creating their own.
Variety of coins doesn't possess a threat to cryptocurrencies, because people have chance to choose among them and thus they don't (are not supposed to) pump one single coin and that would actually be a true risk, for fast pump leads to even faster dump, after all.
It's true that variety makes it harder to choose in what to invest, but that's a problem for some people, not the market in general.
