It's imprudent to invest in a coin that you don't know much about and make a purchase based only on the video you watched. If we talk specifically about XRP, then we need to take into account that the price can reach ATH only as a result of the positive end of the trial, the end date of which is not known.
Open the chart, check past cycles,
Open google and search for past fud against XRP.
XRP is very bad for people who are not patiently in waiting because that coin often accumulates very long time. During accumulation, most of impatient investors will exit.
I agreed that it is bad if anyone invests money into anything without due diligent research.
