Feature 1: Pool Buying function: As we speak, there are ongoing private sales offering huge profit margin. Usually, normal users cannot join. We can create smart contracts for users to pool together and join these exclusive deals.

Anyway, some ICO doesn't allow pool to join in due to KYC or legal stuff like that. On top of that, what's the advantage of using your service instead of participating in pools directly? You just provide an interface, but they can already participate in pool with existing wallet like MEW.
Feature 2: Group investment: Request permission from your most trusted contacts, see how your friends money moving into/out of their wallets and let them see yours. As a team, have better buying/exiting decisions or discovery of potential new coins.

Feature 3: P2P Trading market: We often find very potential new coins not yet listed on trusted exchange. However, we have to do a lot of KYC and place hard-earned money on new, strange exchanges, or just give up these tokens. We have support for the latest coins, and we can help you find the highest bidder for your tokens.

Feature 4: Crypto Millionaire planner: We all want to be millionaires, but most of us lack discipline. Our wallet let you know how many BTC you should save every day to reach your goal or the moon. For example, you should buy 0.05 BTC each day, if you aim to 1 millions in 2021.
