From the very beginning, it is very clear that bitcoin is highly volatile crypto currency and therefore its valuation tends to flactuates and varies according to market demand and supply and in evidence of this statement, the valuation of bitcoin was sky high in the last Decembers month but then started deflating in the beginning of this year and now after 8 months, has been deflated to a very low extent but there are even assumptions that valuation will again inflate in the coming months of this year so you need not to regret on your decision and just continue investing into bitcoin.
