Those ICO companies are just trying to sell their own market. the owners of those companies are equally investing on bitcoin, because they knew that bitcoin is the big player of the market .

it is true that it is because of bitcoin that blockchain was created by satoshi. but the different between blockchain and bitcoin is that blockchain is independent while bitcoin is dependent on blockchain. so blockchain can survive without bitcoin.

i don't think if bitcoin can reach 20k this year. because one of the reason why we use bitcoin is because of the low transaction fee. we know what happen to to the fee when  bitcoin was upto 20k.[the fee was very high] and again too, some country never agree for bitcoin to be used or allowed in their country.

the reason why we really need bitcoin, is because, we want to be fully in control over our money and  not others or the authorities to control it for us.

we all know about laws of supply and demand. [SUPPLY states that the quantity of a good supplied (i.e., the amount owners or producers offer for sale) rises as the market price rises, and falls as the price falls. Conversely, the law of DEMAND  says that the quantity of a good demanded falls as the price rises, and vice versa.] the power behind bitcoin value is in supply law. WHY? Because the more people around the world or countries accept bitcoin and make use of it, the more it have value.

we all known that bitcoin is not controlled  by anyone, and we equally know that the government like to control it subject in all ways. so, when they see anything that will make them lose control or makes them not to control their subjects in all their financial activities [like bitcoin], they get angry and try to put all their  effort in order to stop it.
