This has not been decided and assuming that has been is a dangerous way to invest.
Nothing has been decided. The whole thing is volatile.
But it is fact that the vast majority of alt coins will fail. There will be new ones and some will survive but not all. It is also a fact that btc drives this market. When it goes down, alts go down more. Could this change? I don?t know, but it would be a huge change. The concept of an anti-fragile store of value like btc is the exciting thing here for me.
I?m not saying don?t diversify. I have over 100 cryptos and I am only 30 percent btc. But that is a very risky position. And I don?t look at them as lotto tickets. When the market cycle happens and profits come, profits are taken. If you didn?t take your profits in December to btc then you lost btc and fiat - plain and simple.
Look at the charts for basically any alt coIn vs btc. Rapid market cycles. Beating btc over the long run has historically been difficult. Perhaps this is easier in the future with a robust derivatives market checking in btc but that derivatives market will ultimately extend to alt coins and when it does, investing in them will become increasingly difficult.
There is absolutely no free lunch here. And investing in projects that are trash or possibly trash (and there are a ton of those) is the way to lose your bitcoin or, if you prefer USD.
