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
If it's for the long term and safe, my advice is to keep bitcoin, don't buy sell buy sell your bitcoin, you have to focus on one point, if you want to be safe, stay focused on bitcoin, don't move to another coin, especially if you don't understand what you are buying because bitcoin is the king of cryptocurrency but if you want to buy altcoins I also recommend eth top 2 coins in marketcap and the king of altcoins for now focus on these two things
