The value of Bitcoin has several implications on the general cryptocurrency market. As the downtrend continues we've had a substantial reduction in the coin market capitalisation and the price of most altcoin are in their lows. I really do hope that there's a change in fortune as I see bitcoin approaching $15,000, in few days.
$15000 will be the last bottom and will be a very strong support in my opinion,
because Bitcoin is also down 70% from ATH now, big investors like institutions too I'm sure they will keep the price of bitcoin,
but I don't know because $20k is already broken and we are in $18k, hope there's a rebound this weekend
its strong support based on high time frame and not visit yet for many years. If this level not broken , trend reversal will happen immediately. Today looks like huge investors or whales want to push bitcoin price. Institutional will fill their bag in this level.
