Never ''panic buy'' after the raise already happened sometimes it turns out well but mostly it will suck and u will have a few sleepless nights. Buy coins when they been stable for a few days

Also better to stick to older and estahblished coins which are known; the profit may not come fast but if u have patience u are sure to make some profit over time if u just hodl patiently

Also looking at the actual technology might be a good idea tho i myself suck at that tbh
