Re:       Registration Statement on Form S-8

Ladies and Gentlemen:

We have acted as counsel to Next Technology Holding Inc., f/k/a WeTrade Group Inc. (the “Company”), in connection with its Registration Statement on Form S-8 filed with the Securities and Exchange Commission (the “Commission”) on the date hereof (the “Registration Statement”), pursuant to the Securities Act of 1933, as amended (the “Securities Act”). On April 16, 2025, the Board of Directors of the Company (the “Board”) approved the Next Technology Holding Inc. 2025 Equity Incentive Plan (the “Equity Plan”) for the issuance of up to 80,000,000 shares (the “2025 Shares”) of the Company’s common stock (“Common Stock”) under the Equity Plan, which was subsequently approved by the shareholders of the Company, effective as of June 20, 2025. The Company previously filed a Registration Statement on Form S-8 (File No. 333-288503) with the Commission (the “Commission”) on July 3, 2025, registering 80,000,000 shares of Common Stock issuable pursuant to the Plan (the “July 2025 Registration Statement”). On September 16, 2025, the Company effectuated a 200-for-1 reverse stock split (the “Reverse Stock Split”) of its Common Stock. Based solely on the Secretary’s Certificate (as defined below), the Company did not issue 10,000,000 of the 2025 Shares prior to the Reverse Stock Split, therefore, Rule 416(b) of the Securities Act of 1933, as amended, proportionately reduced the amount of undistributed Common Stock to 50,000 shares of Common Stock. The Company desires to register an additional 9,950,000 of Common Stock (the “Residual 2025 Shares”). This opinion letter is furnished to you at your request to enable you to fulfill the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act in connection with the Registration Statement, and no opinion is expressed or may be implied herein as to any matter pertaining to the contents of the Registration Statement other than as to the valid issuance of the Residual 2025 Shares.

As the basis for the opinion hereinafter expressed, we have reviewed originals or copies of the following:

We have relied upon the foregoing and upon certificates and other assurances of officers of the Company and others as to factual matters without having independently verified such factual matters. We have assumed for purposes of this opinion: (a) information contained in documents reviewed by us is true, complete and correct; (b) the genuineness and authenticity of all signatures on original documents; (c) the accuracy and completeness of all documents delivered to us and the authenticity of all documents submitted to us as originals; (d) the conformity to originals of all documents submitted to us as copies; (e) the accuracy, completeness and authenticity of certificates of public officials; (f) the legal capacity of all natural persons; and (g) the due authorization, execution and delivery of all documents by parties other than the Company.

We are opining herein as to the Wyoming Business Corporations Act, as amended, and we express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction, or as to any matters of municipal law or the laws of any local agencies within any state.

Based on the foregoing, and subject to the qualifications, assumptions and limitations stated herein, we are of the opinion that the 2025 Residual Shares have been duly authorized for issuance pursuant to the Equity Plan, and when issued in accordance with the terms of the Equity Plan, will be validly issued, fully paid and nonassessable.

We expressly disavow any obligation to advise you with respect to future changes in law or in our knowledge or as to any event or change of condition occurring subsequent to the date of this letter. This opinion is for your benefit in connection with the Registration Statement and may be relied upon by you and by persons entitled to rely upon it pursuant to the applicable provisions of the Securities Act.

We consent to the filing of this opinion as Exhibit 5.1 to the Registration Statement. In giving these consents, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission.
