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.

Bitcoin is the most popular but there is still competition, however it's clearly evident that bitcoin is dominating them all.
Hence, we have to be careful in investing altcoins because they would not move well if bitcoin will not be performing well, altcoins depend on bitcoin.
