What are your thoughts on using past charts(candlesticks) that similar current ongoing charts(candlesticks) to make price predictions?
There is no prediction that is 100% accurate, so the results of technical analysis will be subjective depending on how traders interpret price history which they then process into an entry signal. Actually, it is not a matter of trust but of possibility, in fact traders are very flexible to change the type of analysis used if it is not profitable enough.
I have been in trading for a long time and traded in forex, option, stock and crypto market. From my experience i can say that technical analysis will work in crypto as long as there isn't any new events in action. Any negative or positive news about the market can prove a TA totally wrong. This is the reason i try not to trade when there is any upcoming news events or the market is volatile due to any ongoing news events.
