Yes, it is very long, but at least it has some visual symmetry. What is much more important is very trending keyword, ethereum - second largest crypto atm with huge market capitalization and growing. .Investments goes very well with keyword. There will be some competing alternatives for this, like .finance, .cash, .money, .fund, etc, but still not so much great alternatives.
As for pricing, many new gTLD investors will want this name, and can offer probably low XXX for quick flip, which can at least pay for already paid renewals. For end user, if you can keep it and wait for good offer, this can fetch anything between $5000-$15000 imo in 2017. The renewal for .investments seems to be pretty hefty ($70-$120, depending on registrar), but I would advise to invest 1 more renewal for this name (seems like you are deciding whether to renew it or not if I am checking that correctly, WHO status is "pending delete").
I have also some ideas for this name, you can PM me if you like.
