The way Bitcoin is going, $1000 to $20,000 and then to $6,500 and all the bans worldwide and Bitcoin used in many kinds of criminal activities.
I will come back to Bitcoin after 5 years. If Bitcoin is there, it will go the silver way. Just as Silver was $80/ounce in 1980, Bitcoin can go back to $400.
If you come back to bitcoin in 5 years you most likely won’t even be able to afford to buy 0.05 bitcoin’s. With the next halving in 2020 plus the gradual increase in price due to new adopters if you’re leaving now you moght as well stay away because you’ll be kicking yourself.
5 years in crypto is like 500 years in normal history (for example, in the history of gold). There is no way to tell with certainty if Bitcoin will still be there then. With that said, though, I'm dead certain that crypto will still be around and likely expanding slowly into different fields of real use. What I want to say is that Bitcoin is definitely not the only pebble on the beach. So far all crypto at large has been a massive vehicle for speculation, while technical and technological advances and advantages are mostly irrelevant, at least as long as you could safely move your coins to and fro. But all cryptocurrencies are virtually the same in this regard. Right now, it is entirely a matter of personal preferences and choice among traders.
However, if they choose some other coin as their favorite speculative tool instead of Bitcoin, the latter is doomed. Then it can be assumed hypothetically that it will turn into silver. I for one don't believe in the "silver" scenario myself, though, because real silver has intrinsic value and industrial application as well as in jewelry so its price can't be 0, no matter what. But this is not the case with Bitcoin (as with any other cryptocurrency, for that matter).
