You might have been right at that time but right now I dont think you are right in thinking that Bitcoin has no competitors. Coins like Ethereum and IOTA pose a very serious threat to the number one position of Bitcoin. And I think that lightning network is the only thing that can save it from being replaced as the king of the crypto markets.

All those FUDsters that where saying year ago how Bitcoin would fail because another currency would take over get proven wrong year after year. The more time Bticoin is alive, the stronger it gets and the bigger the network effect. Sorry but there will not be a Bitcoin 2.0. Bitcoin will go to 100k+ per coin in the next 5 to 10 years, it will absorb all the value researched in the field if not directly through protocol improvements then through sidechains.

Bitcoin will remain the only solid coin. The only coin that survived for the longest time (other coins can't claim this unless they invent a time machine).
There will be alts that pump really hard and make people millionaires, but no alt is going to surpass Bitcoin's strength and solidity. No coin will get a bigger marketcap. In the long term people holding 21+ BTC will be rewarded by history with rich-tier status for seeing the value in it before most people did. Do not let the FUDsters trick your mind or the trolls try to derrail the excellent job being done by Core devs.

Let's continue then our path towards inevitable triumph.

Alternative crypto-currencies also gain momentum, seeking to gain a foothold in the non-cash world of the future. Here are the five main competitors of bitcoin with a capitalization of more than $ 5 billion: Etherium, Ripple, IOTA, Dash, Lightcoin.
