Altcoins are not reliable for the long term, the successful tactics with alts is buying when no one is buying and selling when you are in profit, it is not something you cab hold for a long period of time.
If Bitcoin falls altcoins will lose value 2x, and even more, it is not a goof choice for a long term play obviously, but do not buy the idea that altcoins can't make you rich, the best money I made from crypto are all from altcoins, find the good ones and hold, when altcoins season begins you will be rewarded big time vs holding Bitcoin.
Lot's of the altcoins project where not even built for longevity, so finding the good one to hold might just be a waste of time. At best once you hold an altcoin for a short term and you've seen a seemingly double of your investment, you should take your profit almost immediately.
This kind of advise of waiting for an altcoin season to buy, is what has made a lot of people invest wrongly, we sometimes talk more about the success stories of how we where able to get good rewards from our altcoins investment, then talk less on the risk involved, just the way people that have invested in Tron are currently counting their losses, we should always balance the discussion by identifying the risk factors in some of this altcoins.
