I think it's monero because they use cryptonote

I still don't know what it is, can you tell me?

but what is the benefit of the project?

I want to test MVP too. Where can I find it?

And how many coins can you park for a first time?

Dear users!
Thank you for interest to our minimal product Republia Bank.
The minimal product Republia Bank is designed for users to get to know about the bank and the “parking” system from the initial stage of the project. “Parking” is a voluntary deposit of coins. Upon registration each user gets 10 conventional units, those interests that users will receive from “parking” process, will be converted into real RPB coins. Interest rates on the type of “parking” will change in order to understand the structure of banking system. 20% from “parking” in case of parking again. Functions of MVP Republia Bank: Deposit of funds; Receiving interests from “parking”.
Enjoy Republia Ecosystem!

if everything will be the way they writing in their documentation then yes

Moreover this coin should grow with the introduction of new mechanisms. what could be better than stable forecasted growth without sharp falls?

I think the coins that are perfect for long-term investments are: Neo, Litecoin and EOS.

as for me, I always choose altcoin which is ranked top 10-15 in coinmarketcap.
