Might be a useful tool, to predict when Altcoin would go up... but already there are bots who do trading for humans, they see if the trend is up and then do the trade.

So at this age of such good AI uses, these apps too come up, its expected.

As for crypto, right now speculation is the fiat and traditional economy would be in crisis or slowdown for people to turn to gold and BTC...

in a way its really good because BTC was designed as alternative to fiat economy. It's testing ground for BTC and exciting.

I am all for crypto because I don't trust Govt. and so fiat currency and believe BTC and cryptos are superior currency and they would survive, even if there is some financial system collapse.

Although, I don't want any complete collapse of the system, that will be instability and chaos, let us see.

But it is good nevertheless that BTC is given a chance to prove its worth as a hedge currency because of the macro economic conditions prevailing in US and other places of negative interest yielding bonds, devaluation of Chinese currency, the US-China trade war, the possibility of US fiat currency getting devalued because of its fiscal debt which is a lot.

A slight economic slowdown is very provable and BTC is therefore on bull territory. Anyway, all speculations, but they are good reasons for BTC to rise up again!!!!

As for exact time when this would happen for one to invest, for those these Apps would be handy giving the index number based on analysis from data procured from crypto exchanges.
