It must be clear by now after 14 years of Bitcoin launch that it's the only coin that can survive on it's own. Survival rate of other alts is also visible and we can safely conclude that they are not worthy to be tried because of there short life. Success in Bitcoin may not be in short duration but if we invest for long duration, while investing in alts is just like gambling with your money.
Such alts (Trump and Melania) with keep coming with time to time and we just need to have one stance for them i.e. stay away from them.
Bitcoin is not a get rich quick scheme. You must wait a long time to succeed from Bitcoin. If you ask Bitcoin to give you quick profits like Altcoins, then you will be wrong. Because Altcoins are like gambling. It is absolutely impossible to say when it will happen. You may win from Altcoins at some point but your money is at risk. Here the chances of losing your money are higher. In the long run, it may not give you a big benefit or you may lose everything.
But the chances of you losing from Bitcoin in the long run are very low. I think Bitcoin is the only digital currency from which the chances of getting profit are very high for long-term investment. All types of investments have risks but it is less or more. It is better to invest in Bitcoin than to face the risk of losing money by investing in other digital currencies in the long run. The chances of losing are slightly lower here.
