Bitcoin is the most reliable investment among all the cryptocurrency, Bitcoin gives you rest of mind when you invest into it because you can't lose unless you sell your coin below the price that you bought it because of fear as the market starts to correct. Bitcoin gives profit to those individuals that have patience and are willing to hold Bitcoin for a very long time. You can make profits in short term when you invest into Bitcoin but it can't be like the profits of someone that didn't sell early and was holding as the price of Bitcoin keeps increasing. Bitcoin is the best investment and also the best currency right now therefore selling your Bitcoin too early isn't a wise decision. If you don't sell and continue holding you can sell your one Bitcoin for more than $1 million in the future.
Yes Bitcoin is the most reliable investment coin among all cryptocurrency coins. But if you invest in bitcoins and you fail to hold it for a long time then you may not expect anything good from your invested bitcoins. So the prerequisite for investing in Bitcoin is to set the right goals according to your plan and then invest and hold for a long time. Bitcoin investors must have different plans with their investments so they continue to invest in Bitcoins according to their plans. If we want to achieve something in our life then we have to set a sign and act accordingly to reach the goal. Just like in bitcoin investing everyone should set a price target for bitcoins then when they reach that price you should sell them otherwise you shouldn't.
Those who invest in Bitcoin and are patient can gain a lot from their investment but those who don't have patience can't gain much because they invest in short term.
