In my opinion,the market will not flow if we just hold it.Buying can increase the value of bitcoin or even altcoin.We need to circulate this to have a good value and a healthy market.Bitcoin prices are generated by demand and supply.When HODL wants to be tempted to sell when the price is high.But I think there will always be people who sell and there will always be people who buy and always hold bitcoin,therefore we can see in the market where the movement is always there and there is always a price change and there is always buying and selling in the market.
