The lower risk percentage makes Bitcoin a good choice for long-term investment. It cannot be denied that everyone who understands this will of course choose Bitcoin.
However, that doesn't mean that Altcoins are a bad choice, there are times when Altcoins can produce much bigger profits, but again, as I said earlier, everything depends on the risk and what you need to know is that every possible profit will be worth it with all the risks involved faced.
Alternate cryptocurrency is a good investment but it must be in a reportable coins otherwise any shitcoin that doesn't possess the quality of can be easily a waste of investment such as newly listed tokens in the market, that is why many people prefer using their hard earned money to invest into bitcoin to secure their investment. We know that bitcoin is volatile but the volatility of altcoin can't be compared with bitcoin hence is possible of losing its value at any given time and anymore moments.
Altcoins may be a good investment for you but for me I can never consider to leave Bitcoin and invest in any altcoins or shitcoins because I can't invest in a coin that has a higher risk of losing my money in a blink, altcoins are too risky so it is better to invest in an asset that has cleared the doubt of many over the years and Bitcoin is that coin. There's something some people don't get about bitcoin investment, Bitcoin is an asset that has stood the test of time, it is reliable, safer, easier and affordable by applying the DCA which gives the ease to be investing a portion of your income from time to time without being under pressure of any kind as your most targets is accumulating a huge amount of Bitcoins for long term profits so it's as simple as that instead of investing on those coins that has no future as they can pump and dump at any period of time and you lose all your investments.
Whenever people talk about investing on altcoins I do laugh because most of the people that invest in altcoins are newbies who are just new in the crypto space but as soon as reality happens to them and they lose all their money they begin to cry and feel bad about it. Any one who have witnessed the story of some folks who invested large amount of money on altcoins and they were scammed because the coin just dumped immediately after they invested in it, you will understand that Bitcoin is surely the right investments anyone can think of. I have come to understand that the reason why some investors do consider some altcoins is because they spend most of their time monitoring the activities of the market and when they see that a particular coin rose to ×100 to x1000 they raise their eyebrows and feels that such coin is good to invest in but at last they still lose their money.
Altcoins don't act like Bitcoin that it's dump is an opportunity for investors to buy at a DIP price before the price skyrockets as in most cases when an altcoin starts dumping, it's for real and due to the fear of not selling at a lost price most people that invest in it end up losing everything. I was lucky to have been advised earlier by a relative who lost about $5k on altcoins which is a huge amount when converted to my country's currency, he advised me that I shouldn't be enticed by the huge pump of some altcoins that I should only focus my energy on Bitcoin because he has been a big time victim to altcoins and he wouldn't like anyone close to him to experience same thing he did. Ever since he gave me that advice I have always sticked to Bitcoin alone and I can never consider investing on any damn fucking altcoins or shitcoins other than Bitcoin.
