    public class CryptocurrencyPriceInfo{

        private HashMap<String, CryptocurrencyJsonPriceDataDto> fileds = new HashMap<>();

        @JsonProperty("date")
        private String date;

        @JsonAnySetter
        public void setFiled(String field, CryptocurrencyJsonPriceDataDto value) {
            fileds.put(field, value);
        }

        @JsonAnyGetter
        public HashMap<String, CryptocurrencyJsonPriceDataDto> getFields() {
            return fileds;
