Well, cryptocurrencies are currently undergoing a massive adoption period. Whereas the previous bull run was largely based on speculation and perceived value, this bull run will largely be dependent on use cases. Cryptocurrencies as a whole are gaining media attention every day. CNBC recently had a "Fast Money Goes Crypto" episode, Forbes & Bloomberg have at least one article on Bitcoin a day, I recently saw an IBM Blockchain ad on national television, and Trump even banned purchases of Venezuela's shitcoin (although this may look bad if someone doesn't know what crypto is). People are becoming more aware of crypto as a part of everyday life, even if the initial Bitcoin hype-train has died down. Litecoin and several other cryptos have launched payment processors that make it much easier for merchants and retailers to accept cryptos as real methods of payment.
Moreover, given the additional attention that the United States' state and federal governments have paid to the market, crypto has gained legitimacy. A few states have now begun to accept tax payments in crypto, and the SEC has stated it would likely take a "regulate, don't hinder approach." Combined with the recent statements from the Congress' economic report on cryptos, the state of the market is overall bullish.
Finally, the largest exchange, Binance, is moving to Malta in an attempt to avoid excessive regulations from the HK government. They have also announced a MAJOR development with possible altcoin/USD fiat pairing in the near future. This is yet another bullish event for all of crypto.
