Bitcoin has several advantages, some of them are as follows:

It was the first cryptocurrency and the project that brought the novelty of blockchain technology, that is always an advantage, because mentally people are inclined towards the known brand.

The mining system and its difficulty have raised the cost of production of each BTC, this is a factor that affects the price increase.

Bitcoin is the most used and accepted cryptocurrency and people have greater facilities to convert FIAT money.

Since there are big businessmen and a high volume of people using Bitcoin, then there is a lot of speculation and this becomes an attraction.

In short I think that the Altcoins have lacked a truly aggressive strategy that I bet on practical use, in doing so, you can make a big difference.

The truth is that Bitcoin is a trackable cryptocurrency and its blockchain can be analyzed, however, what some scammers do in which little by little they are finding ways to filter accounts and disperse the illicit and thus even somehow lose traces, but Computer experts are able to detect all these movements, I think you will always be exposed to hackers, it is best to take good care of private passwords and not manage large funds in the Exchanges, because they are the most vulnerable.

The expectations are quite positive, because despite the ups and downs that have occurred in this year 2019, cryptocurrencies have been expanding and it is expected that by 2020 growth will be accelerated for both Bitcoin and other new projects, the amount of Cryptocurrencies have grown incredibly and those projects are looking for a position in the market, many will get it in the year 2020.

The truth is that the negative opinions about Bitcoin and the cryptocurrencies used by Cuban are not convincing, in fact Bitcoin does have intrinsic value and the millions of people are using it.

It is clear that cryptocurrencies have some disadvantages and one of the biggest challenges is scalability, it is desired that projects can process millions of transactions in minutes always efficiently and is a problem for most cryptocurrencies.

I believe that taxes can affect Bitcoin to some extent, however, we must be clear that most of Bitcoin and cryptocurrency transactions are related to trading and not so much in the purchase of goods and services. I share the opinion of
avikz in the sense that it is better to have a rigorous legal framework than to have none.
