Cryptocurrency total market cap explosion

If anyone is following the total market cap for all cryptos, would have noticed that it has exploded in the last few weeks. At the start of the year it was around 30b, a month ago it was 200b and now it's around 293b. It might reach 400b + by the end of the year. This shows just how much new money is flowing into the crypto space, but with Bitcoin holding around 50% dominance, there is going to be a big shift soon as Coinbase is adding many Altcoins which are due to explode too.
