top100cmc and binance.py

# 1. Download the top 100 from CoinMarketCap.
# 2. Download all USDT-based pairs from Binance.
# 3. Print out a list of the top 100 coins tradeable on Binance.
#
# The theory is that the top coins are going to perform best
# in a bull market. With this information we can build a momentum 
# strategy based on the top coins only.
# Suggestion usually is to check the top 100 coins monthly,
# then rebalance the portfolio.
