I usually Invest a very small amount of bitcoin to another coin because I know this time is very crucial to invest in any new coin or even in an old coin.
Any suggestion from your side which is good for long term
Just a piece of advice based on my experience before;
At some time in the future, there may be the time you will regret your decision about converting some of your Bitcoins to some altcoins. Why? Because not all altcoins are good, some are only hype, so be careful.
I experienced this before when I am new in cryptocurrency, Bitcoin is the most cryptocurrency I have before, and during that time, as what newbies do, they are attracted on some altcoins some are because of hype, so I tend to convert my Bitcoins to random altcoins and ended getting rekt while Bitcoin is not.
It obviously requires research and analysis before someone invests in an altcoin, especially if they are going to convert their Bitcoins into another altcoin which is already something very risky since we all know that Bitcoin is the safest of them all when it comes to price plunges. So one should be very careful about the altcoin that they choose to invest in because altcoins are generally not to be held for a very long term.
If a trader thinks that they are not being able to find a good coin to invest in and are uncertain, they should simply let their funds stay in Bitcoin and keep it for the long term, Bitcoin never disappoints if it isn't sold quickly because history says that Bitcoin recovers its price eventually.
