If we want to trade short term, I think using Bitcoin is enough, but if we want to invest long term , I think asset diversification is a better choice
I think Bitcoin is great for both short term and long term investment, because Bitcoin is the most reliable of all the crypto currency markets. I have been trading in different crypto currencies for a long time, but any crypto currency, even if it is the best crypto currency in the market, has a high risk of loss.
We often trade in crypto currencies that have high volatility so that we get a good profit, but often the same volatility becomes a big loss for us. My experience till date has taught me that whether long term investment or short term trading Bitcoin is the best. Where our assets are the most secure, even if their value falls, we do not worry about our assets.
