Anybody who is going into cryptocurrency should choose bitcoin and then focus on a long time investment plan because there is every chance of making profit in the future even though profit is not guaranteed, invest with the amount you can afford to loss.
Making a profit from Bitcoin is not a constant issue where you cannot be sure even though your chances are very high because the decentralized volatile price market depends only on supply and demand. If you decide to invest in Bitcoin, you need to keep the profit motive away from greed because most newbies buy short-term to get high profits.
In investing in Bitcoin for the long term, you should continue to save for holding than for profit. I do not agree with the fact that there is no guarantee of getting profit. I think that by continuing to accumulate Bitcoin in the DCA method, you can get high profit from the amount of holding you get. The demand for Bitcoin will be infinite in the future but the supply amount is fixed so it's worth should be increase.
