Well, honest persons will come and chose btcz because the already known facts, with no ico, no premine.
As for other coins, mostly are SCAMs, pumps and dumps, etc. etc. etc. coins, for which you`ll have to risk IF you don`t know any of the inside members.
Hence, with BTCZ, you know from start that this has started from genesis block, you can find that out for youself.
It has natural growth, and most probably you're funds should be safer in BTCZ compared to ANY OTHER ICO/AIRDROP/PREMINE/NAAAAME IT.

So, what`s the purpose of your question from below?

Either choose it and invest in it if you`re confident enough, else go and invest in any ICO/AIRDROP you want.

It`s still... a free world.
