I cannot agree on the fact that Bitcoin will keep on declining. It may reach to $6000 and rise from that. Besides, the demand of Bitcoin is increasing consistently and it will gradually affect the price positively. So, let's wait to see what happens ahead.
It is increasing, but you have to take into account the coins that are being mined every day and there's a lot of them, 1800 exactly. So, for the market to turn bullish all those coins have to be either bought or held, plus some of the buy orders have to get filled for the candles to turn green. This is why BTC needs enormous hype to keep climbing. If the attitude turns neutral it will immediately go into the negative due to fresh coins flooding the market. Normal assets don't face these problems.
