Often times people's investments are very personal to them. if you have 100% of your net-worth in one thing  it may cause you to overlook important details. people are sold the idea of one thing and even if proven wrong they will refuse to believe it no matter what you show them. with that being said Bitcoin is the highest appreciating asset ever existing  going up 6.5 million X in its lifetime. Bitcoin will reach new all time highs one day, and will probably remain #1 market cap for a long time. however it has many flaws that should be discussed and cannot be swept under the rug.
