Before the launch of cryptocurrency, bitcoin is the initial initiator of the appearance of other crypto coins, and the first is usually identical to the experimental designation. Well, for me bitcoin is an experimental coin, I think it's natural that there are some shortcomings in bitcoin, because in those days (the days of Satoshi Nakamoto made the first coin 'BITCOIN' in 2009) computer technology isn't as sophisticated or as powerful as it is today such as ASIC Miner, CGMiner, BFGMiner or possibly other series, if any (sorry that's all I know) but the fact's bitcoin has managed to fix the deficiencies that occur in conventional money. So obviously, aside from being the originator of other coins, bitcoin has also given birth to new ideas especially in IT, that's it the emergence of some of the 'MINER' tools I mentioned earlier. Not only that, the presence of bitcoin accompanied by his brother named 'Blockchain' LOL.
Although bitcoin is considered to be disruptive for some industrial sectors, especially finance and banking, but blockchain can be utilized to be a great opportunity, because this technology has a more secure, transparent, fast, and efficient, which can run without bitcoin.
The presence of another crypto seems to have been planned well in advance perhaps after the launch of bitcoin. The main purpose of this altcoin is to cover the weakness of bitcoin which is due to its limited supply of only 21 million coins, not only that every new altcoin emerges usually accompanied by innovation which is expected to improve the deficiency of bitcoin its slow transactions. I think this's where Mr. Satoshi Nakamoto, as he was able to predict the future state of bitcoin which will experience some problems during his journey.
I can clearly see that there are other cryptocurrencies that are beginning to dethrone bitcoin, showing off there quick and secured transactions, though bitcoin continues to be the king. What does bitcoin need to improve state your opinions.
I think bitcoin's pretty good and right now we can only wait for a positive decision from the government, that's all (While biting a finger)
