In terms of long-term investment, only Bitcoin will give us something good, shitcoins are never suitable for investment, they only attract people, and short-term investors invest in shitcoins hoping to get rich quick and only get disappointed, never get yourself involved in the temptation of investing in shitcoins. Because they are not suitable for investment, they are only created to make people poor. Bitcoin is the only investment that is a profitable and safe investment for the long trem, besides, the acceptance of Bitcoin is constantly on the rise, and Bitcoin will achieve more greatness in the future. So all in all, there is no other investment better than Bitcoin.
There is probably no other coin more trusted than Bitcoin in the crypto world. That is why most of our portfolio should be filled with Bitcoin. If you want, you can keep some percentage of the portfolio (a limited amount) in some altcoins or some memecoins as alternative investments. I am saying this from my personal freedom and you can also freely keep a small percentage of the portfolio in other coins. There are some convenient reasons for this, one of which is to gain real knowledge about crypto and gain the ability to differentiate Bitcoin from cryptocurrencies.
Real knowledge is important so that you can even warn others about cryptocurrencies. However, the amount of cryptocurrencies invested should not be too large. Investing up to 10% of the total investment in cryptocurrencies may be the right decision, but I think it is right to limit it to 3-5%. Another advantage of this is that if you are lucky, you can earn some money from it, but the chances of losing are high. Before investing in Sitcoin, you must try to gain a deep knowledge of the risks and do this with utmost caution. Since there is a lot of risk here, you must enter into personal freedom, do not invest more money on the advice of others.
