This truth is actually very simple. The amount of funds in the entire cryptocurrency market is quantitative. Bitcoin has gone up， the reasons is investors invest bitcoin after selling the altcoin. This is the blood-sucking effect of bitcoin.
People have different reason why they want to earn cryptocurrency, some of them are for living and others just want to have a good asset that is profitable for long time so we cannot determine when the market price will pump or dump.
We choose cryptocurrency investment in order to look for either short term or long term that will result in profit or benefits. Long term investment plan is most profitable which is better with the Bitcoin and then Ethereum while other Altcoins are also available for us in which we can invest for little profit as these Altcoins are less valuable so we can treat it easily in short time.
