First of all, no one knows for sure. But here are a few reasons at play:
SUPPLY : Miners currently receive a 12.5 BTC reward for every block that they mine, but Nakamoto’s protocol also requires that the mining reward is halved every 210,000 blocks, or approximately four years. The next miner halving will take place within two years, approximately in early June 2020 depending on hashrate, bringing the rewards down to 6.25 BTC per mined block.
DEMAND: While the number of transactions are trending upwards (see Bitcoin Number of Transactions excluding Popular Addresses, it seems that there is not as much new interest in investing into bitcoin at the moment. Interest has stabilized, but may not be outstripping demand. Google Trends - Web Search interest - Worldwide, 2004 - present.

I think biblical explanation was not the reason for the dumping and pumping of bitcoin price. Cryptocurrency like bitcoin are the currency we just use for our financial and material need. The reasons behind the situation now of crypto market are those people who are panic selling which is considered as the flow of demand and supply. Because they sell and sell and sell,supply are more than the demand which brings the price drop. So,if there are people and investors that continue to buy and hold until supply is out,then the price will go up.
