Despite the negativism of many bitcoin haters, I believe that bitcoin will continue to be popular and powerful in five years, although by that time there will probably be much more sophisticated altcoins and maybe bitcoin will no longer occupy the first place in dominance, but because of the growth that this market will experience in the coming years, even being out of the top 5 its price will be above the $100,000 mark.
I think it's normal to happen, there will always be negative and positive to cryptocurrency. But the challenge is to cryptocurrency users if they assume that the negative of cryptocurrency is only temporary and they will always keep the money in cryptocurrency, then within five years, cryptocurrency will grow.
But my confidence in altcoin is going to exceed the bitcoin, I am not sure yet. Bitcoin will always grow for a long time, and bitcoin will be the biggest market in cryptocurrency. I am a bitcoin investor and so far altcoin has advantages over bitcoin but I am still reluctant to move my investment to altcoin, like to ethereum.
