My holding worster than you some of my coins worth 10K dollar now its worth nothing means nothing . Not only one coin some of coins trading more than 10$ now its worth less than few Cents . I dont say its end of crypto . I could say its end of scam ICO projects.
I agree with your opinion that the price of coins that fall is not the end of crypto, but there are some coins from ICO projects that are not optimal and unprofessional so that the coins produced are not sold on the market. The result is that the coin is worthless.
But let's see the prices of major crypto coins like Bitcoin, ETH, Monero, LTC, ZCash, Dash or BNB all have high prices and large capitalization in the crypto market. This is a sign that crypto will never die.
