The subject of diversification have been discussed extensively across several boards and from those discussions, I have learnt that diversification is a very delicate thing and often lead many into problems. How many businesses you have is not what will make you rich but how well you have been able to perfect what you do. In other words, it is better to be known for something, like a brand, than to be known for everything because wealth are created through branding. If you have some funds to invest in a business, perfect the business and from the proceed, you can start buying Bitcoin to save for future. I don't support spreading your funds to several cryptocurrency because you may lose your money in the process.
If you do something with a product that spreads and branding it to everyone then it can be an impressive effort. The effort to spread it can be within your community or even among all communities. Branding through a product is a good business strategy. I agree with you with this strategy your initial losses will be higher but as you gain experience you will continue to profit.
Diversification may be better than this but this method may not be good for everyone. If your amount of money is relatively small or to increase experience diversifying your business may be a good decision but I doubt this strategy will be applied to all classes of people. They may not feel comfortable applying a specific strategy. There are many different aspects involved in applying strategies in investing in digital assets and physical assets. Diversification should be based on knowledge and experience while investing in digital assets.
