Hold for long term is best thing to do for now, but we have to choose good coin that have strong fundamental, like LTC, EOS, TRX, XLM, XRP, BNB. in 1 years all these coin has potential to raise more than 10x because the market cap still low and the price still undervalued. Second thing is keep patient waitimg for bull market is key to recover loss.
I agree, I also do not pay attention to temporary losses, except for the originally planned long-distance, I think if you dont touch the coin for several years and, if possible, increase the portfolio of small coins, then in 3-5 years you can be very pleasantly surprised
