That was a good analysis because till date we hope to see another altcoins season but haven't. Although we all waited for the season to come in 2019, hope we still holding some altcoins portfolios will be able to stayonger than expected till 2020. Hope the genuinely altcoins projects be found in the coming years. Scammed projects have really distorted the progressive will of altcoins.
Although, this maybe not the year for altcoins, still if you truly believe in the altcoins that you are holding and that you are investing at, then better to just hold it for now and wait for its perfect moment, or sell it for Bitcoin and Ethereum, still depends how you do investigate about the altcoins, if they are still worth investing or you already need to let them go.
