The only secure coins for me with how the market is going right now is a stablecoins. Thanks to Stop-loss, I converted my holdings to stablecoin automatically, but now maybe it's a good entry point again, and I'd advise you to make your huge Bitcoin holding and perhaps some Ethereum and top 5 coins. We have proven to be durable overtime and do not turn to massive losses overnight as we saw with so many coins listed on the 2018 exchanges.
