Obviously, you made a very common mistake by buying SNM at the price level where your friend was selling this coin. And where your friend got a profit, you got a loss. So after all, it's not about the capitalization of the coin, since such a mistake can be made when buying any coin.
No me and friend buying/selling was not on the same day. My friend books profit 3 months before I lost. Reason for my losing ws delisting which was unexpected because some good upgrade news was shared in the twitter and I was expecting short term profit but things goes totally against me. I want to say that low cap coins are very risky, can give you big profit even in bear market but loss is also big.
I never buy low cap coins for taking profits in the next bullrun season. Now, almost all crypto coins have cheap prices, why we must buy low cap coins if the top coins with high market caps are in cheap prices? It is untrue if low cap coins are easy to get 100x profits, the low cap coins are getting rarely to increase 100x. There are too many failed coins, so I believe the top coins with high market caps are the best option for investment now.
Anyway, I only get low cap coins from bounties or airdrops but I'm not sure if they can make me to get profits. Most of the low cap coins dropped too significantly during the bearish season. Many of them are unlikely to reach again its ATH in the next bullrun season.
Bounties coins are new and listed in small exchanges , sometimes only in dex. We are talking about those coins which are listed in big exchanges like Binance, Kucoin. These coins rising speed is much better then any other coins, sometimes 10x in just 2 days but I agree that if price not rised then these low cap coins are behaving like a dead coin and holders have to wait long (more then six months) for any breakup. Low risks coins are better choice to invest in bear market.
