Broker with leveraged trading + big list of alt coins

I was looking to find a Trading broker that has a big list of cryptocurrencies with maximum leverage (ideally 100x)?

So far I've found Bitmex and Cryptorocket. (Etoro's list of alt coins is a bit small and only 2x leverage so not so good)

For anyone else interested..

Bitmex, I can only see a total of 8 cryptos on offer.
With the smallest max leverage being 20x for XRP,etc. (100x for BTC).

Cryptorocket,
Has 35 crypto instruments (including crosses) and told me they have 100x leverage on each of them.
I don't know much about these guys so not sure how solid they are.

Would be good to find somewhere that is offering some sort of leverage on the top 100 crypto's, probably not possible, but what have you found that offers the most diversity and leverage?

thanks.
