i prefer to buy it and keep it long term, because i believe bitcoin will continue to have a high value every 4 years, so don't have to follow bitoffer sites or other similar sites, i see bitcoin price hitting 13k too i think maybe it will touch it again $ 15k in soon
That's a good idea I would say because BTC is very powerful coin in crypto currency and it has the capability to break any barrier even the 20k which happened in 2017, even my long-term goal is to hold till 2025 because I think it will go over the moon again in few years.
Why not take some profits and leave the rest portfolio? because the price might likely experience a dip anytime from now Christmas is approaching some hodlers might exchange some of their portfolio to fiat to buy stuffs for celebrations definitely that is going to affect its price, however if your price perceptive is long term then you have to be patience as price action had been very bullish in the last couple of days probably next year might mark another remarkable year if the price can break the last ATH of 2017.
