Can you please give some more info about your service? Maybe teaser about how is it going to work and what technical data you are focusing to analyze currencies?
Tradingview is doing good but needs more authors for cryptocurrencies.
Sure, so I'm still early stage in developing a solution and really want to first hear problems before I make a solution. But here is my idea - I create several kinds of portfolios - Simple one -> holds major cap coins and only rebalance twice a year / -> more advanced portfolio analyzes top 100 coins and picks and rebalances portfolio frequently (maybe bi-weekly etc. depends on backtesting results) / -> Aggressive portfolio focusing on smaller cap coins and more frequent rebalancing.
To analyze currencies: Use technical indicators (Momentum, RSI, MACD etc.), social engagement, GitHub activity, maybe using machine learning techniques (text-mining or K-means clustering). To allocate use own proprietary method.
It is to help people who don't have time to own research but wants to allocate their wealth to cryptos and still wants good returns.
