Investing Haven's crypto currencies and blockchain technologies will continue to be the determinant of Bitcoin's crypto currency markets, according to 2019 forecast; however, the record increases in Bitcoin may not continue. 
Within the Belgian-based Inveting Haven website, the value increase in Bitcoin, which is the determinant of the crypto-currency markets, may not be as strong as in the past in the years ahead, in the context of various predictions of the crypto-currency markets and block chain technologies in 2019.
In its forecast for Investing Haven, Bitcoin futures in 2019 were predicted to be more valued as Bitcoin was the first to introduce two-way trade in the Bitcoin market since it was first introduced to the market.
With the overall downward trend in the crypto-currency markets, the Bitcoin price is expected to rise to $ 25,000, while forecasts suggest an upward trend in Bitcoin price, but the probability of a previous record increase is low.
